Page 49 Problem 8 Answer

Given: There is a given equation 66×2/3%

Find: Write each percent as a fraction in simplest form and as a decimal to the nearest hundredth. Approach: Here, A percent is a portion of 100

so to write a percent as a fraction, Write the percent in the numerator and 100 in the denominator.

A percent is a portion of 100 so to write a percent as a fraction, write the percent in the numerator and 100 in the denominator. Then reduce if possible:

To write 66×2/3% as a decimal, we need to convert 2/3 to decimal form by dividing 2 and 3.

Since we need to round to the nearest hundredth, divide up to 3 decimal places:

Rounding to the nearest hundredth then gives 66×2/3%≈0.67.

Page 49 Problem 18 Answer

Given: At a concert, 20% of the people are wearing black dresses or suits, 1/4 are wearing navy, 0.35 are wearing brown, and the rest are wearing a variety of colors (other).

Find: Write the percent, fraction, and decimal for each color of clothing. Approach: It is given that 20% wore black, 1/4 wore navy, 0.35 wore brown, and the rest wore other colors.

It is given that 20% wore black, 1/4

wore navy, 0.35 wore brown, and the rest wore other colors. We need to write the percent, fraction, and decimal for each color of clothing. Black

Other To find the percent, we must first find the combined percent for black, navy, and brown. Adding the percentages gives 20%+25%+35%=80%.

The percent for others is then 100%−80%=20%.

Since Other and Black have the same percent, they must also have the same fraction and decimal. The fraction and decimal for Other is then 1/5 and 0.2.
