Describe the result of adding a large positive number and a smaller negative number. -
answer✔smaller positive number, same as ignoring the signs and subtracting the smaller
number from the larger
how do you convert a fraction into a decimal? - answer✔divide numerator by denominator
What is the key step that must be performed in order to add or subtract unlike fractions? -
answer✔find the least common denominator
how do you divide one fraction by another? - answer✔invert the divisor and multiply
numerators together and denominators together
how can you convert a decimal into a percent? - answer✔multiply by 100 and add the %
sign or move the decimal two places to the right and add the % sign
how do you convert a fraction into a percent ? - answer✔convert it to a decimal, move the
decimal point to places to the right and add the % sign
How do you change a decimal into the nearest equivalent fraction? - answer✔multiply the
decimal by the desired denominator. The result becomes the numerator in the fraction
what are two different ways that a ratio may be expressed? - answer✔as a fraction, by
placing a colon between the two numbers, by using the word to between the two numbers
what is a proportion? - answer✔statement of equality between two or more ratios
what is meant by the root of a number? - answer✔two or more equal smaller numbers that
when multiplied together equal a specified number
how do you find the square of a number? - answer✔multiply the number by itself
what is a common method of making computations involving very large or very small
numbers more manageable? - answer✔convert the numbers into scientific notation by
using powers of 10

gravity
what is the term that describes the angle between the relative wind and the chord line of an
airfoil? - answer✔angle of attack
what are the factors that cause an airplane wing to stall? - answer✔angle of attack exceeds
critical value and airflow separates from upper surface- becomes turbulent
what are the principle effects that result from lowering the flaps while in flight? -
answer✔lift increase, drag increase, stall speed decrease
