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%

Step-by-step explanation:

Method 1:

The original fraction is $\frac{3}{10}$

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

Multiply the top and bottom by 10

$\frac{3}{10} * \frac{10}{10} = \frac{30}{100}$

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

Method 2:

The original fraction is $\frac{3}{10}$

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 $\frac{3}{10}$

$\frac{3}{10} = \frac{x}{100} \\10x = 300\\x = 30$

cross-multiply to solve the equation
