Question

50 is what percent of 80

Answer 1

50 = x% * 80

50 = x/100 * 80

50 = x/10 * 8

Multiply 10 on both sides.

500 = x * 8

8x = 500

Divide 8 on both sides.

x = 500/8

x = 62.5


50 is 62.5 percent of 80.

Answer 2

50 is 62.5% of 80

Divide 50 by 80 to get the decimal:
$\frac{50}{80} = 0.625$

Multiply the decimal by 100:
$0.625 \times 100 = 62.5$
