When painting my bedroom i used 3 1/2 liters of blue paint and 2 1/4 liters of red paint. how much paint did i use in all

Hi there!

To solve this problem, we need to find the total amount of paint used by adding the two fractions.

First, we need to find the common denominators below adding.

1/2 = 2/4
1/4 = 1/4

The common denominator is 4.

Now, we add the mixed numbers together:

3 2/4 + 2 1/4 = 5 3/4

Since 5 3/4 can't be simplified, the answer is:

5 3/4 liters of paint

Hope this helps!

Heya!
You have used 5 3/4 paint in all.
.
3 1/2 + 2 1/4
= 5 (2+1)/4
= 5 3/4
