Answer 2

Answer:

a ) 65%

b ) 210%

c ) 2%

d ) 1235%

Step-by-step explanation:

To convert a decimal to percentages, do the steps below :

Step 1 : Change the decimal into fractions.

a ) 0.65 = $\frac{65}{100}$

b ) 2.1 = $\frac{210}{100}$

c ) 0.02 = $\frac{2}{100}$

d ) 12.35 = $\frac{1235}{100}$

Step 2 : Simplify the fractions :

a ) 0.65 = $\frac{65}{100}$

             = $\frac{13}{20}$

b ) 2.1 = $\frac{210}{100}$

         = $\frac{21}{10}$

c ) 0.02 = $\frac{2}{100}$

            = $\frac{1}{50}$

d ) 12.35 = $\frac{1235}{100}$

             = $\frac{247}{20}$

Step 3 : Multiply 100 into the fractions and there goes your percentage!

a ) 0.65 = $\frac{65}{100}$

             = $\frac{13}{20}$

( $\frac{13}{20}$ × 100 )% = 65%

b ) 2.1 = $\frac{210}{100}$

         = $\frac{21}{10}$

( $\frac{21}{10}$  × 100 )% = 210%

c ) 0.02 = $\frac{2}{100}$

            = $\frac{1}{50}$

( $\frac{1}{50}$ × 100 )% = 2%

d ) 12.35 = $\frac{1235}{100}$

             = $\frac{247}{20}$

( $\frac{247}{20}$ × 100 )% = 1235%
