Mathematics
1 answer:
Volgvan3 years ago
6 0

Answer & Step-by-step explanation:

(2/5 + 3/4) * [ 3 - (1/4 : 1/5)]

When you see this sign, : , it usually means to divide the numbers because they represent some form of a ratio. So, we will divide 1/4 by 1/5.

First, do all of the operations in the parentheses ().

(2/5 + 3/4)*[ 3 - (1/4 : 1/5)]

(23/20) * [ 3 - (5/4)]

(23/20) * (7/4)

Now, we multiply 23/20 by 7/4.

(23/20) * (7/4)

161/80

This number can not be simplified so we will keep it as it is.

So, the answer to this expression is 161/80
