Answer 1

`(c)\ (40)/(100)\cdot 84`

`(e)\ 0.4\cdot 84`

Explanation:

Given

`40\%\ of\ 84`

Required

Two options with the same value

First, calculate the value of:
`40\%\ of\ 84`

`40\%\ of\ 84 = 0.40 * 84`

`40\%\ of\ 84 = 33.6`

So, we have:

`(a)\ 40\cdot 84`

`40\cdot 84 = 40 * 84`

`40\cdot 84 = 3360`

`(b)\ 0.4/ 84`

`0.4/ 84 = (0.4)/(84)`

`0.4/ 84 = 0.00476`

`(c)\ (40)/(100)\cdot 84`

`(40)/(100)\cdot 84 =(40)/(100)*84`

`(40)/(100)\cdot 84 = 0.40*84`

`(40)/(100)\cdot 84 = 33.6`

`(d)\ 84 / 40`

`84 / 40 = (84)/(40)`

`84 / 40 = 2.10`

`(e)\ 0.4\cdot 84`

`0.4\cdot 84 = 0.4 * 84`

`0.4\cdot 84 = 33.6`

By comparison, we have:

`(c)\ (40)/(100)\cdot 84`

`(e)\ 0.4\cdot 84`

have the same value as:
`40\%\ of\ 84`
