Question

Help me please help me please.

Answer 1

p = 0.09375

Explanation:

simplify the fractions within the fractions first to make it easier:

`(3)/(10) = 0.3` and
`(4)/(5) = 0.8` and
`(1)/(4) = 0.25`

set up the equation then cross multiply:

`(0.3)/(p) =(0.8)/(0.25)`

0.3 x 0.25 = p (0.8)

0.075 = 0.8p

divide both sides by 0.8:

p = 0.09375
