Question

which group does not consist of equivalent numbers a. 8/20, 0.4, 40% B. 35/1-, 3.5, 350% C. 6/12, 0.5, 50% D. 5/8, 0.7, 70%

Answer 1

Numbers in group D are not equivalent.

Explanation:

Group A,

`(8)/(20)`, 0.4, 40%

`(8)/(20)=0.4`

40% =
`(40)/(100)=0.4`

So all three numbers are equivalent.

Group B.

`(35)/(10)`, 3.5, 350%

`(35)/(10)=3.5`

350% = 3.5

So all numbers of this group are equivalent.

Group C.

`(6)/(12)`, 0.5, 50%

`(6)/(12)=0.5`

50% =
`(50)/(100)=0.5`

All numbers in this group are equivalent.

Group D.

`(5)/(8)`, 0.7, 70%

`(5)/(8)=0.625`

70% = 0.70

Therefore, numbers in group D are not equivalent.
