Question

Which of the following percents can also be expressed as a mixed number? 310%,49%,7.4 % 0.001% show the work.

Answer 1

Only 7.4% can be expressed as a mixed number.

To convert 7.4% to a mixed number, we can divide 7.4 by 100:

7.4 ÷ 100 = 0.074

Then, we can express 0.074 as a mixed number by writing it as a whole number plus a fraction:

0.074 = 0 + 74/1000

Simplifying the fraction:

74/1000 = 37/500

Therefore, 7.4% can be expressed as the mixed number 0 37/500.

310%, 49%, and 0.001% cannot be expressed as mixed numbers because they are greater than 100% or less than 1%.

Answer 2

3.1

Explanation:

To express a percent as a mixed number, we need to divide the percent by 100 and convert it to a mixed number.

Let's do this for each option:

310% = 310/100 = 3.1

3.1 can be written as the mixed number 3 1/10.

49% = 49/100 = 0.49

0.49 cannot be expressed as a mixed number because it is less than 1.

7.4% = 7.4/100 = 0.074

0.074 cannot be expressed as a mixed number because it is less than 1.

0.001% = 0.001/100 = 0.00001

0.00001 cannot be expressed as a mixed number because it is less than 1.

Therefore, the percentage that can be expressed as a mixed number is 310%, which is equivalent to 3 1/10.
