Question

Aleysha is painting one of her bedroom walls blue. On Monday, she painted 3 of the 4 walls, but decided she didn't like the color. On Tuesday she switched colors and repainted 2 3 of the walls green. How much of the blue wall had been painted green at the end of Tuesday?

Answer 1

Hey there,

In order to solve this equation we are going to subtract 2/3 by 3/4.

To add or subtract fractions we need to make sure that they have a common denominator:

• 2/3 and 3/4 (common denominator would be 12) so 8/12 and 9/12

Now that the denominators are the same we can subtract the two fractions:

• 9/12 - 8/12 would equal to 1/12

That means that 1/12th of the wall still needs to be done.

Therefore 8/12 of the wall had been painted green at the end of Tuesday.

Hope I helped,
