Expert verified

50% of 160 is 80.

Step by step solution

Step 1. Definition of percent:

Percent of a number is defined as the ratio of number and 100.

Step 2. Formula Used.

The ratio of part x of some number y is equal to the percent is written as.

$\frac{x}{y} = \frac{p}{100}$

Step 3. Find the percent proportion.

Percent = 50, x = 80 and y =?

$\frac{x}{y} = \frac{p}{100} \frac{80}{y} = \frac{50}{100} [crossmultiply] 80 \times 100 = 50 \times y 8000 = 50 y [dividebothsideby 50] \frac{8000}{50} = \frac{50 y}{50} 160 = y y = 160$

Hence, 50% of 160 is 80.
