Summer Review Sheets — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A snack bar sells 14 smoothies at $6 each. Total sales are $84 .
Multiply 14 smoothies times $6 each: 14 times 6 equals $84.
2. The top number in a fraction is called the numerator.
The numerator sits on top of the fraction bar and tells how many parts you have. In 34, the numerator is 3.
3. A camp stores 336 life jackets in 7 equal closets. Each closet has 48 jackets.
336 divided by 7 equals 48. You can check: 7 times 48 = 336.
4. A number rounded to the nearest ten of 0.47 is 0.5.
When rounding 0.47 to the nearest tenth, look at the hundredths digit (7). Since 7 is 5 or more, round up from 0.4 to 0.5.
5. Seven boats each carry 23 passengers. Together they carry 161 passengers.
Multiply 7 times 23: 7 times 20 is 140, plus 7 times 3 is 21, so 140 + 21 = 161 passengers.
6. The bottom number in a fraction is called the denominator.
The denominator sits below the fraction bar and tells how many equal parts the whole is divided into. In 34, the denominator is 4.
7. A swim instructor works 8 hours a day for 5 days. She works 40 hours per week.
Multiply 8 hours per day times 5 days: 8 times 5 equals 40 hours per week.
8. A decimal that has two digits after the point is in the hundredths place.
The second digit after the decimal point is in the hundredths place. For example, in 0.25, the 5 is in the hundredths place.
9. A campground rents 216 tents over 9 weekends. That is 24 tents per weekend.
216 divided by 9 equals 24. You can check: 9 times 24 = 216.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
numerator
→ the top number in a fraction
a whole number and a fraction together
denominator
→ the bottom number in a fraction
fractions that name the same amount
mixed number
→ a whole number and a fraction together
the top number in a fraction
equivalent fractions
→ fractions that name the same amount
the bottom number in a fraction
Correct matches: numerator → the top number in a fraction; denominator → the bottom number in a fraction; mixed number → a whole number and a fraction together; equivalent fractions → fractions that name the same amount.
