Accuplacer math placement Test 34 Questions with Verified Answers How to divide fractions - CORRECT ANSWER Multiply by the recipricol of the second fraction (ex. 3/4 5/7 is rewritten as 3/4 x 7/5) How to add or subtract decimals - CORRECT ANSWER 1. line up the decimals 2. fill in spaces with zeros 3. bring decimal STRAIGHT DOWN 4. Add using correct place value How to divide decimals - CORRECT ANSWER • If number you're dividing by is a decimal, then divide as usual and bring decimal point in the number being divided straight up. • If number you're dividing by IS a decimal, then make it not a decimal by pushing decimal to the right as much as needed. Push decimal exact same amount to the right in the other number. How to change a decimal to a fraction - CORRECT ANSWER Starting from the decimal point, count the decimal places (to the right). If there is one decimal place, put the number over 10 and simplify. If there are two places, put the number over 100 and simplify. If there are three places, put it over 1000 and simplify. Four places, put it over 10,000 and simplify. How to change a fraction to a decimal - CORRECT ANSWER Ex: 7/25= 7 x 4 25 -- ---- 25 x 4 = 100 So 7/25=.25 11/20= 11 x 5 55 -- --- 20 x 5 = 100 So 11/20=.55 Adding and subtracting decimals - CORRECT ANSWER 1. Vertically line up numbers at their decimal points. 2. Use zeros as placeholders to make each number thee same number of places. 3. Bring the decimal point down below. 4. Add Vertically to find the sum; subtract vertically to find the difference. Multiplying Decimals - CORRECT ANSWER 1. Multiple numbers as if whole numbers. 2. Then count total number of decimal places in the factors and add them (Ex: 2.2 and 2.33 has three total decimal places) 3. Add the total number of decimal places to product, counting left to right (Ex: 2.2*2.33 = 5126 --> 5.126 final answer) Dividing decimals - CORRECT ANSWER 1. Change divisor (the # outside the box thing) to a whole number by moving the decimal point to the right as many places as it takes to make a whole number. 2. Move the decimal point of the other number the same number of spaces to the right. 3. Complete long division problem. Change a percentage to a fraction - CORRECT ANSWER 1) Write the number in front of the % symbol as the numerator over a fraction bar. 2) Write 100 as the denominator. 3) Discard the % symbol. 4) Reduce fractions whenever possible. Change a decimal to a percentage - CORRECT ANSWER 1) Move the decimal point two places to the right. 2) Add a % symbol. Change a fraction to a percentage - CORRECT ANSWER 1) Change the fraction to a decimal by dividing the numerator by the denominator (ex. 9/50 = 9 divided by 50) 2) Change the decimal to a percentage by moving the decimal places two places to the right. 3) Add a percent symbol. Find the mean / average of a set of numbers - CORRECT ANSWER 1) Add up all numbers in set. 2) Divide by the total number of items in the set. Whenever a number is raised to the first power, it remains - CORRECT ANSWER The same. (Ex: 9 raised to first power is 9) Whenever a number is raised to the zero power, it equals - CORRECT ANSWER Zero How to multiply fractions - CORRECT ANSWER Multiply numerators, then denominators the slope-intercept form of an equation of a line - CORRECT ANSWER y=mx+b Ratio - CORRECT ANSWER The quantitative relation between two amounts showing the numbers of times one value contains or is contained within the other Exponent - CORRECT ANSWER A quantity representing the power to which a given number or expression is to be raised, usually expressed as a symbol beside the number or expression (Ex 3in 23=2•2•2) Root - CORRECT ANSWER A number x is another number, when multiplied by itself a given numbers of times Similar triangles - CORRECT ANSWER Two angles of a triangle that measures equal to another Liner equations - CORRECT ANSWER Involving two variables it's graph is a straight line in the Cartesian coordinate system Slope - CORRECT ANSWER Measure of the steepness of a line,or a section of a line, connecting two points System of equation - CORRECT ANSWER A set or collection of equations that you deal with all together at once or math problems that include more than one equation Factor - CORRECT ANSWER A circumstance, fact, or influence that contributes to a result of the outcome and numbers that are multiplied together to obtain a product Leading zeros - CORRECT ANSWER Zeros between the decimal point and the first non zero in a number smaller than one Absolute value - CORRECT ANSWER The mangnitude of a real number without regard to its sign Arithmetic Sequence - CORRECT ANSWER An ordered list of numbers and the sum of the terms in a series Numerator - CORRECT ANSWER Which tells how many parts you have Denominator - CORRECT ANSWER How many part of a whole Common factor - CORRECT ANSWER A number that divides exactly into two or more other number Area of a circle - CORRECT ANSWER The diameter of a circle, circumference, and the cord Area of a triangle - CORRECT ANSWER A=1/2bh the point at which two sides of a triangle meet perimeter - CORRECT ANSWER A figure is the total distance around the edge of the figure Power - CORRECT ANSWER A number that says how many times to use the number in multiplication
