Question

7 times as much as the sum of 1/3 and 4/5

Answer 1

Well first we want to divide 1 by 3 , which is 0.3  ,  Now we need to divide 4 by 5 which is 0.8 . 

We have our answers but 7 needs to be added by their sum so lets put them together by adding them : 0.3 + 0.8 = 1.1.

Now lets add 7 and 1.1 all together , which is 8.1.

Answer 2

The expression will be written

7 (1/3 + 4/5)

First we add 1/3 and 4/5 by finding a common denominator.

1/3 = 5/15
4/5 = 12/15

So now we have

7 (5/15 + 12/15)

Add inside the parentheses

7 (17/15)

now multiply

7×17/15 = 119/15 =

7 and 14/15
