Question

5/8 =25/40,6/7=12/27,2/7=4/14,-8 /7 =-72/56 state which of the following are true in this option

Answer 1

Answer:

a) True

b) False

c) True

d) False

Step-by-step explanation:

To find true or false we have to find equivalent fractions by multiplying the denominator and numerator with same number

a) 5/8 = 10/16 = 15/24 = 20/32 = 25/40

Ie 5/8 = 25/40 = True

b) 6/7 = 12/14

Therefore 6/7 = 12/27 = False

c) 2/7 = 4/14 = 6/21

ie 2/7 = 4/14 = True

d) -8/7 = -16/14 = -24/21 = -32/28 = -40/35 = -48/42 = -56/49 = -64/56 = -72/63

Therefore -8/7 = -72/56 is false
