What is seven minus one and three fifth?

Answer 1

(3 1/5) - (1 3/5) : If we borrow 1 from 3, then 3 1/5 becomes 2 6/5 [1 = 5/5, and 1/5+5/5 = 6/5]. Now can subtract 3/5 from 6/5, and subtract 1 from 2:

6/5 - 3/5 = 3/5. 2-1 = 1. So the answer is 1 3/5.

Answer 2

3 2/5 - 1 3/5 = 2 7/5 - 1 3/5 = 1 4/5

Or...seventeen fifths minus eight fifths is nine fifths, ie one and four fifths.

Answer 3

7 - 13/5 = 7 - 8/5 = 35/5 - 8/5 = 27/5 = 52/5

Answer 4

2 2/3 - 1 = (2 + 2/3) - 1 = (2 - 1) + 2/3 = 1 + 2/3 = 1 2/3.

Answer 5

1 and 1/5 = 5/5 + 1/5 = 6/5
6/5 - 3/5 = 3/5
Answer: three fifths

Answer 6

It is the same as: 7/5 minus 3/5 = 4/5
