Question

Carrie has 2 meters of ribbon. She cuts off pieces of ribbon that are 5/10 meter, 1/10 meter, and 7/10 meter. How long is the remaining piece of ribbon?

Answer 1

`(7)/(10)`

Explanation:

Carrie has 2 meters of ribbon. She cuts off pieces of ribbon that are 5/10 meter, 1/10 meter, and 7/10 meter

Lets add all the cut of pieces and subtract it from 2 meters

`(5)/(10) +(1)/(10)+(7)/(10)=(13)/(10)`

Now we subtract 13/10 from 2 meters

`2 - (13)/(10)`

To subtract , make the denominator same

`(2*10)/(1*10) - (13)/(10)=(20)/(10) - (13)/(10)=(7)/(10)`

7/10 meter is the remaining piece of ribbon
