Question

On a recent math assignment consisting of 31 problems, Gianna had 26 application problems, and the rest involved only computation. What percent of the problems were only computation? Round your answer to the nearest tenth of a percent, if necessary.

Answer 1

To find the percentage of computation-only problems, subtract the number of application problems from the total, divide the remainder by the total number of problems, and multiply by 100. Out of 31 problems, with 26 application problems, 16.1% were computation-only.

Step-by-step explanation:

The question asks us to calculate what percent of the problems on Gianna's math assignment were only computation, given that out of 31 problems, 26 were application problems. To solve this, we first find the number of computation-only problems by subtracting the application problems from the total number of problems: 31 - 26 = 5 computation-only problems.

Next, we calculate the percentage of computation-only problems against the total number of problems. We set up an equation where 5 (computation-only problems) / 31 (total problems) equals some fraction over 100, and then cross-multiply to solve for the percentage. This gives us (5/31) * 100 which equals 16.129…%. Rounded to the nearest tenth of a percent, the answer is 16.1%.

Therefore, 16.1% of the problems were only computation.
