Gentry poured 23.5 ounces of milk and 7.75 ounces of cream in a mixing bowl.How much more cream could Gentry add to the bowl if the capacity of the bowl is 35.5 ounces?

Answers

Notice that because the capacity of the bowl is 35.5 ounces, but there has already been 31.25 ounces total added to it (23.5 ounces + 7.75 ounces), all that needs to be done is subtract 31.25 from 35.5:
35.5 - 31.25 = 4.25 ounces of cream could be added

Answers

The most accurate way would be the fourth answer, because to estimate 66% of 47 you need to round both as closely as possible. 66% rounds closest to 2/3, and 47 is closest to 48

The last option is the most accurate. Here is how you can solve it:
1) Turn fractions into decimals
2/3 =0.666666667
1/4 =0.25
1/4 =0.25
2/3 =0.666666667

2) Multiply
0.666666667 x 50 = 33.333333...
0.25 x 48 = 12
0.25 x 50 = 12.50
0.666666667 x 48 = 32

3) To find what 66% of 47 is, you turn 66% into a decimal and multiply it by 47.
0.66 x 47 = 31.02

66% or 47 is 31.02

2/3 x 48 equals 32, and since it is the closest to 31.02. Therefore, the last option is the best option.
