Answer:

7a and 7b are true, 7c is false.

Explanation:

The image shows that she has 9/10 meters of the string available.

She wants to use 3/5 meters, so the part remaining is


(9)/(10)-(3)/(5)=(45-30)/(50)=(15)/(50)=(3)/(10)

Basically, the statement 7a is true, because with that difference we can find the string remaining. Also, with this results, we can say that 7c is false, becasue 1/5 meters is not the string remaining, it's 3/10.

Additionally, 7b is true, because 3/5 and 6/10 are actually equivalent factors, observe that if you multiply the first fraction by two, you'll get the second fraction.

1st - True.

Reason: The remaining shaded portion is
(9)/(10) and she will use
(3)/(5) of it, so remaining will be =


(9)/(10)-(3)/(5)=(3)/(10) parts

2nd - True.

The given fractions
(3)/(5) and
(6)/(10) are equal.

3rd - False

As calculated above in the 1st part, 3/10 parts will be left, so this question is false.
