Answer 2

Question :-

$5 \cfrac{2}{7} + 3\dfrac{1}{2}$

Aim :-

• To add all the terms

Let us first convert the mixed fractions to improper fractions.

$\cfrac{37}{7} + \dfrac{7}{2}$

The terms are unlike. In order to add them we have to take the LCM (LEAST COMMON MULTIPLE) of the denominators.

LCM of 2,7 = 14

We have to multiply a factor with the numerator and denominator of the fractions so that the denominator is 14 for both the fractions.

$\dfrac{37 \times 2}{ 7\times 2} + \dfrac{7 \times 7}{2 \times 7}$

$\dfrac{74}{14} + \dfrac{49}{14}$

Now that the denominators are the same we have to add them.

$\dfrac{74 + 49}{14}$

$= \dfrac{123}{14}$

We have to convert the answer to mixed fraction.

$= 8 \dfrac{11}{14}$

Hope it helps!

Happy day!
