Of the 120 math tests, 47 were Bs. What percent of the math tests were Bs? Round to the nearest whole percent.
Answer:
39.17%
Step-by-step explanation:
Answer:
39%
Step-by-step explanation:
Percent is ALWAYS out of 100, and the unknown is percent so our first part of the equation will be %/100. Now our second part of equation: is/of
Of represets whole the total, and we have our key word “Of the 120 math tests”. We have our total: 120; 47 is our part so second part of equation: 47/120.
Our equation so far: %/100 = 47/120 now we need to multiply the numbers that we have diagonally: 100% x 47; 47/100 we’re multiplying so we’ll move two 0s to the right. Answer: 4700
Now, we’ll divide 4700 by 120. 4700/120. Answer: 39.1666666667. Round to nearest whole means round to nearest ones.
Thus, the answer is 39.
