fraction 1 and 2 over 5 units
fraction 1 and 1 over 5 units
fraction 4 over 7 unit
fraction 2 over 7 unit

Answer 1

The Answer is A, fraction One over Two units.

Answer 2

The answer is A.) Fraction 1 and 2 over 5.
1/5 = 0.2
1÷5 = 0.2
1/2 = 0.5
1÷2 = 0.5
2(0.2+0.5) = 1.4
1.4=1.41/1
1.4/1 x 10/10 = 14/10
14÷2=7
10÷2=5
7/5= 1 2/5
