Rachel ate 1 4/6 brownies, and brandy ate 6/7 of a brownie. how many brownies did they eat altogether?​

Step-by-step explanation:

1 4/6 + 6/7 = 2 11/21

Problem: 4/5, which is 4 / 5.

Step-by-step explanation:

To solve this problem, we must divide 4 and 5.

4 / 5 = 0.80

0.8, 4/5.

Another way is to change 4/5 into a Decimal.

It's 0.8 because Four (Fifths), If you multiply 4 / 5, both terms by 2, you get 8/10 and you write it as a decimal of 0.8

Eight - Tenths.

Last Way:

Change into a decimal be comparing other fractions,

8/10 = 4/5 and 8 / 10 has a decimal of 0.8.

Hope this helps!!
