Question

Rewrite with the LCD

Answer 1

1/4 + 3/8

Rewrite with the LCD (lowest common denominator)

Remember : the denominator is just the bottom number on a fraction.

Let's look at both of our given fractions denominator's.

4 & 8 → What do both of these numbers have in common? They both go into 8!

How many times does 4 go into 8? → Twice

How many times does 8 go into 8? → Once

So, because of that, we must multiply the top number (numerator) of each fraction with either one, or two.

First fraction : 1/4 × 2/2 =2/8 → So, our first fraction changes.

Second fraction : 3/8 × 1/1 = 3/8 → However, our second fraction changes.

So, our new question looks like this : 2/8 + 3/8

If you wanted us to answer this question, we simply need to add the top numbers (numerators) with one another because both fractions have the same bottom numbers (denominators).

2 + 3 = 5

So, our answer is 5/8 and our question rewritten with the LCD is : 2/8 + 3/8
