Evaluate the expression: 75 - 52 + (18 x 9) =

• 191

• 185

• 213

• 187

Answer explanation

To evaluate the expression, first perform the multiplication: 18 x 9 = 162. Then, subtract 52 from 75 to get 23. Finally, add 162 to 23 to get the result of 185. Therefore, the correct answer is 185.

Taylor is helping decorate tables with flowers for a graduation celebration. She has 7 dozen tulips. She will put 1/2 dozen tulips in each vase. How many vases does she need?

• 13

• 4

• 12

• 14

Answer explanation

To find the number of vases needed, divide the total number of tulips (7 dozen) by the number of tulips per vase (1/2 dozen). 7 dozen tulips = 7 x 12 = 84 tulips. 84 tulips ÷ 6 tulips per vase = 14 vases needed.

A scientist had 3/4 of a bottle of a solution. She used 1/6 of the solution in an experiment. How much of the bottle did she use?

• 1/8

• 1/6

• 1/4

• 1/2

Answer explanation

To find out how much of the bottle she used, multiply 3/4 by 1/6. (3/4) * (1/6) = 1/8. Therefore, she used 1/8 of the bottle.

Answer explanation

To find the total number of books shipped, multiply the number of packages (98) by the number of books in each package (144), resulting in 14112 books shipped.

Cora created a model to represent a fraction problem. Which of the following equations matches the model she created?

• 1/3 x 1/4 = 4/12

• 1/2 x 2/4 = 2/8

• 1/2 x 2/4 = 2/32

• 1/4 x 4/2 = 4/8

Answer explanation

The correct equation that matches the model created by Cora is 1/2 x 2/4 = 2/8.

Which description is equivalent to 6 + (3 x 7)?

• add 6 and 3, then multiply by 7

• multiply 3 by 7, then add 6

• multiply 6 by 3, then add 7

• add 6 and 7, then multiply by 3

Answer explanation

To find the equivalent of 6 + (3 x 7), first multiply 3 by 7 to get 21, then add 6 to get the final result.

Select ALL expressions in numerical form that represent: double twelve then add fifteen.

• 12 + 12 + 15

• 15 + (12 x 2)

• 11 x 2 + 12

• 12 x 2 + 15

Answer explanation

Insert parentheses to make the statement true: 72 - 8 x 6 - 5 = 64.

• 72 - (8 x 6) - 5

• (72 - 8) x (6 - 5)

• 72 - 8 x (6 - 5)

• 72 - (8 x 6 - 5)

Answer explanation

To make the statement true, insert parentheses around 8 x 6 to get 72 - (8 x 6) - 5 = 64, which simplifies to 72 - 48 - 5 = 64. Therefore, the correct choice is 72 - 8 x (6 - 5).
