Question

The ratio of 1.3 to 32 is the same as the ratio of 3.9 to

Answer 1

The ratio of 1.3 to 32 is the same as the ratio of 3.9 to 96

Step-by-step explanation:

The ratio of 1.3 to 32 is

`(1.3)/(32)`

which must be the same as

`\frac{3.9}{\text{Unkown Number}}`

Therefore, we have

`(1.3)/(32)=\frac{3.9}{\text{Unkown Number}}`

Now, cross multiplication gives

`1.3(\text{Unkown Number) =32}\cdot3.9`

Finally, dividing both sides by 1.3 gives

`\text{Unkown Number =}(32\cdot3.9)/(1.3)`

which simplifies to give

`\boxed{\text{Unkown Number =}96}`

which is our answer!
