Question

1/2 - 1/7 3/5 - 4/15

Answer 1

1/2 - 1/7=5/14

3/5 - 4/15=1/3

Answer 2

1) (1/2)-(1/7)=((1×7)-(1×2))/14=(7-2)/14=5/14
2) (3/5)-(4/15)=((3×3)-4)/15=(9-4)/15=5/15=1/3

Answer 3

To solve the expression, let's simplify each fraction first:

1/2 - 1/7 = (7/7)(1/2) - (2/2)(1/7) = 7/14 - 2/14 = 5/14

3/5 - 4/15 = (3/3)(3/5) - (1/1)(4/15) = 9/15 - 4/15 = 5/15

Therefore, the expression simplifies to 5/14 - 5/15.
