Question

can somebody please help me

Two numbers are in the ratio 8:3 one of the numbers is 0.48 work out the the possible values for the other number show how to check that your answers are correct.

Answer 1

Answer: 0.48:0.18 1.28:0.48

Explanation:

Let first number in the ratio 8:3 is 0.48.

Hence,

8 - 0.48

3 - x

Sence,

`\displaystyle\\x=(3*0.48)/(8)\\\\x=3*0.06\\\\x=0.18`

Let second number in the ratio 8:3 is 0.48.

Hence,

3 - 0.48

8 - x

Sence,

`\displaystyle\\x=(8*0.48)/(3)\\\\x=8*0.16\\\\x=1.28`

Answer 2

0.18 or 1.28

Explanation:

Tthe ratio is 8:3 expressed also as
`(8)/(3)`

Let X be the unknown number. We know that one of the numbers is 0.48

Then there are two possibilities

Either
`(0.48)/(X) =(8)/(3)`

or

`(X)/(0.48) =(8)/(3)`

If
`(0.48)/(X) =(8)/(3)`

we get X =
`(3 (0.48))/(8) =0.18`

If
`(X)/(0.48) =(8)/(3)` then

X =
`(8(0.48))/(3) =1.28`
