Sam have 1 1/5 meters of rope he cut off 1/2 meters and use it for a project for school how much real does sam have left

Answer is 7/10

First you find the common denominator which is 10 from doing 5*2.

Then you do 1*2 to get 2 and then also 5*1 to get 5.

Now you have 5/10 - 2/10 = 3/10.

Then you combine the whole and fraction parts and get..

1 - 3/10 = 7/10

( 10-3=7)

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
