Answer: 73,5 meters are cut off and 3/2m are left
Explanation:
1.- Divide 75 in 7/2 that is equal to 21,4...
2.- Take just the 21 and now multiply for 7/2, so it equals to 73,5
3.- Now do 75 less the result of the multiplications that is 3/2
The result is that 73,5m are cut off, that means that 21 pieces were cut equally and that 3/2m are left.
75÷7/2=21,4285...
21×7/2=73,5
75-73,5=3/2
