Question

If 16/9 = 80/n =p/27 what are p and n

a. 47,46
b. 45,46
c.45,48
d.47,48

Answer 1

16/9 = 1.77777
80/n= 1.77777, so replace n with 1.77777 and you'll learn that n equal 45
p/27= 1.77777, so multiply 27 by 1.77777 to get about 48!!!!
45&48 (((:::

Answer 2

c.45,48

Explanation:

Given proportion,

`(16)/(9)=(80)/(n)=(p)/(27)`

If
`(16)/(9)=(80)/(n)`

By cross multiplication,

`16n = 720`

Divide both sides by 16,

`n=45`

Similarly,

If
`(16)/(9)=(p)/(27)`

`432 = 9p`

Divide both sides by 9

`\implies p=48`

Hence, the value of p and n are 48 and 45 respectively,

Option 'c' is correct.
