What are Arithmetic operations? - CORRECT ANSWER - include finding the sum
(adding), finding the difference (subtracting), finding the product (multiplying), and finding the
quotient (dividing).
What are fractions? - CORRECT ANSWER - are composed of a numerator (top number)
and a denominator (bottom number)
, What are proper fractions? - CORRECT ANSWER - numerator smaller than the
denominator. Examples- 1/2 and 7/8
What are improper fractions? - CORRECT ANSWER - numerator equal to or greater than
the denominator. Examples- 6/3 and 2/2

divide evenly into both the numerator and the denominator. Example, with the fraction 4/8 four
divides evenly into both 4 and 8 giving 4/8 ÷ 4/4 = 1/2.
How do you convert an improper fraction to a mixed fraction? - CORRECT ANSWER -
divide the numerator by the denominator to get a quotient of one and then write the remainder
over the original denominator. Example, 15/7 = 2 remainder 1 which is 2 1/7.
When adding and subtracting fractions the denominator must be the same for both numbers. If
you have different denominators what do you do? - CORRECT ANSWER - you need to
find the least common denominator by finding a number that both denominators will divide into
evenly.
How do you multiplying and dividing fractions? - CORRECT ANSWER - simply multiply
the two numerators together to get the numerator of the answer and multiply the two
denominators to get the denominator of the answer.
Formula for simple interest is what? - CORRECT ANSWER - Interest = principal x
