16/32 = 50%

Step-by-step explanation:

A fraction consists of two numbers and a fraction bar:

The number above the bar is the numerator: 16

The number below the bar is the denominator: 32

Divide the numerator by the denominator to get fraction's value:

Val = 16 ÷ 32

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% = p/100 = p ÷ 100.

Divide the numerator by the denominator to get fraction's value:

16/32 =

16 ÷ 32 =

0.5

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

Calculate the percent value:

0.5 =

0.5 × 100/100 =

(0.5 × 100)/100 =

50/100 =

50%;

In other words:

1) Calculate fraction's value.

2) Multiply that number by 100.

3) Add the percent sign % to it.
