how to change mixed number to improper number ?

Sagot :

To change mixed number to improper fractions, multiply the denominator by the whole number and add the product to the numerator, the denominator will be the same.

Example:
5 and 6/9

Step 1:
Multiply the denominator by the whole number.
Bold = Denominator
Underline = Whole Number
5 and 6/9
So 9 x 5 = 45

Step 2:
Add the product by the numerator.
Bold = Denominator
Underline = Whole Number
Simple Text = Numerator
and 6/9
9 x 5 = 45 + 6 = 51
D x W = P + N = N

Step 3:
Copy the denominator
51/9 is the answer.
