Conversion a mixed number 2*1/4
to a improper fraction: 2*1/4 = (2* 1)/4
= (2( 4 )+ 1)/4 = (8 + 1)/4 = 9/4
To find a new numerator:
a) Multiply the whole number 2 by the denominator 4. Whole number 2 equally
(2 * 4)/4 = 8/4
b) Add the answer from the previous step 8 to the numerator 1. New numerator is 8 + 1 = 9
c) Write a previous answer (new numerator 9) over the denominator 4.

Conversion a mixed number
1*4/7
to a improper fraction:
1*4/7 = 1*4/7 = 1 *( 7 + 4) / 7= (7 + 4) / 7= 11 / 7
To find a new numerator:
a) Multiply the whole number 1 by the denominator 7. Whole number 1 equally 1 * 7/ 7 = 7/7
b) Add the answer from the previous step 7 to the numerator 4. New numerator is 7 + 4 = 11
c) Write a previous answer (new numerator 11) over the denominator 7.
