`d=4`

Explanation:

Now multiply 5 by 80 (this will be equal to 100*d)

Your equation (when you do the multiplication):

`100d=5*80`

`d=400/100`

`d=4`

This is your solution:

`d=4`

Answer 2

`color(blue)" dividing numerator/denominator by 20"`

`rArr80/100=cancel(80)^4/cancel(100)^5=4/5larrcolor(red)" in simplest form"`

`rArrd/5=4/5`

`"since the denominators are equal, both 5 "`

`rArrd=4`
