Question

Thomas has 7 1/5 meters of fencing. He used 4 3/5 meters of fencing to surround his yard. How much fencing does he have left?

OA. 3 3/5
O B. 2 1/5
OC. 2 3/5
OD. 3 1/5

Answer 1

Answer: C, 2 3/5

Explanation:

• Let's start by making these fractions easily subtractable

7 1/5 = 6 6/5 (1 is equal to 5/5 so we take that from the 7 and add it to the fraction)

4 3/5 remains the same because this is what we are subtracting

• Set up the equation

7 1/5 - 4 3/5 will be subsituted for 6 6/5 - 4 3/5=? because it's equivilant

• Solve

I like to break this into two parts to make it less complicated, fraction then number

1. Fraction: 6/5-3/5=3/5
2. Whole Number 6-4=2

• Combine back into a mixed number

This will give you the proper fraction for the result of your equation

2+3/5=2 3/5

• Awnser

2 3/5
