Of the hats in Deb's Hat Shop, 1/2 are purple and another 3/10 are red. What fraction of the hats are either purple or red?

4/5

Step-by-step explanation:

Of the hats in Deb's Hat Shop, 1/2 are purple and another 3/10 are red. What fraction of the hats are either purple or red?

The Fraction of the hats that are either purple or red are:

Purple + Red

= 1/2 + 3/10

Lowest Common Denominator is 10

= 5 + 3/10

= 8/10

= 4/5

Therefore, the fraction of the hats tha are either purple or red is 4/5

This is an impossible question. This is because it is less than -80 but when you add the 5 it is -70 therefore it must be -75. But it saying it is below -80 therefore this is an impossible question
