Question

it's for 4th grade math my daughter and I are having trouble figuring this out it's called adding mixed numbers

Answer 1

8 7/3 + 4 1/3

First, add the whole numbers:

8 + 4 = 12

Then, add the fractions:

3/7 + 1 /3

Find the LCM ( least common multiple) of the denominators ( bottom numbers )

21

Then multiply the top and bottom numbers by the same number to obtain 21 at the bottom.

$\frac{3}{7}\cdot\frac{3}{3}+\frac{1}{3}\cdot\frac{7}{7}$$\frac{9}{21}+\frac{7}{21}$

Add the top numbers and keep the same denominator (21)

$\frac{16}{21}$

Join all :

12 16/21

Answer:

$12\frac{16}{21}$
