Examples:

Rewrite mixed fractions into an improper fraction or Whole number \$15 40/10\$

Step 1a

The given fraction is \$15 40/10\$

$1a$

Explanation: The given fraction is \$15 40/10\$, a mixed fraction, a combining of the whole number and a fractional part.

15 represents the whole part and \$40/10\$ represents the fractional part.

Step 1b

The first step is to multiply the whole number part by the denominator i.e.,15 × 10 = 150

$1b$

Explanation: In this step, we multiply the whole number by the denominator of the improper fraction. Here, the whole number is 15, and the denominator is 10.

since, 15×10=150

Step 1c

Add the new product to the numerator. i.e., 150 + 40 =190.

So, the improper fraction is \$190/10\$.

$1c$

Explanation: In this step, add the product to the numerator of the improper fraction. i.e., 150 + 40 = 190.

Step 1d

Simplify the improper fraction by dividing the fraction by 10: \$190/10 ÷ 10/10\$ = 19

Therefore, 15 4/10 as a whole number is simply 19.

$1d$

Explanation: Simplify \$190/10 ÷ 10/10 = 19\$. Therefore, \$15 40/10\$ as a whole number is 19.
