Solve: Adding 3/8 + 2/3 - Unlike Denominators Practice

Question

Solve the following exercise:

$\frac{3}{8}+\frac{2}{3}=$

00:00 Solve

00:03 Multiply each fraction by the second denominator to find the common denominator

00:07 Make sure to multiply both numerator and denominator

00:15 Calculate the multiplications

00:21 Add with the common denominator

00:24 Calculate the numerator

00:28 And this is the solution to the question

Let's try to find the least common multiple (LCM) between 8 and 3

To find the least common multiple, we need to find a number that is divisible by both 8 and 3

In this case, the common multiple is 24

Now we'll multiply each fraction by the appropriate number to reach the denominator 24

We'll multiply the first fraction by 3

We'll multiply the second fraction by 8

$\frac{3\times3}{8\times3}+\frac{2\times8}{3\times8}=\frac{9}{24}+\frac{16}{24}$

Now we'll combine and get:

$\frac{9+16}{24}=\frac{25}{24}$

$\frac{25}{24}$
