Rewrite the fraction in the sentence below as a percentage.
In 2010, a fire destroyed
3/10 of the farmer's crops.

Answer 1

Answer: 30%

Explanation:

Method 1:

The original fraction is
`(3)/(10)`

To convert to a percent, the denominator should be equal to 100 (since percent is per 100)

Multiply the top and bottom by 10

`(3)/(10) * (10)/(10) = (30)/(100)`

Since the numerator is 30, 3/10 as a percent is 30%

Method 2:

The original fraction is
`(3)/(10)`

To convert to a percent, first convert the fraction to a decimal (do 3 ÷ 10)

0.3

10 | 3 0

-30

-------------

0

You get 0.3

Now multiply the decimal by 100

0.3 * 100 = 30

30%

Method 3:

The original fraction is
`(3)/(10)`

`(3)/(10) = (x)/(100) \\10x = 300\\x = 30`

cross-multiply to solve the equation
