1) State whether the following pairs of fractions are equivalent or not : 2/5,10/15 3/7,6/7 9/7 ,1 2/7

2)Reduce the given fractions to their lowest terms.

a) 50/75 b) 65/105 c) 18/81

1)

2/5 ≠ 10/15= 2/3 not equivalent

3/7 ≠ 6/7  not equivalent

9/7 = 1 2/7 = 9/7 equivalent

2)

a) 50/75 = 25*2/25*3= 2/3

b) 65/105 = 5*13/5*21= 13/21

c) 18/81 = 9*2/9*9= 2/9

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
