310%
To determine which of the following percents can also be expressed as a mixed number, we need to convert each percentage into a fraction and then simplify it if possible.
a. 310%
To convert 310% into a fraction, we divide it by 100: 310/100 = 31/10. This fraction cannot be simplified, so it cannot be expressed as a mixed number.
b. 49%
To convert 49% into a fraction, we divide it by 100: 49/100. This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 1: 49/100 = 7/10. This fraction can be expressed as a mixed number as well: 7/10 = 0.7, which is 7/10 expressed in decimal form.
c. 7.4%
To convert 7.4% into a fraction, we divide it by 100: 7.4/100 = 0.074. This decimal is already in its simplest form. Although it is less than 1, it cannot be expressed as a mixed number because the whole number part is 0.
d. 0.001%
To convert 0.001% into a fraction, we divide it by 100: 0.001/100 = 0.00001. This decimal is already in its simplest form. Although it is less than 1, it cannot be expressed as a mixed number because the whole number part is 0.
In summary, the percent that can also be expressed as a mixed number is b. 49%.
