Question

How do you solve `1.1/1.2=n/3.6`?

Answer 1

`n=3.3`

Explanation:

When a fraction is equal to another fraction, we can solve using the method of `color(blue)"cross-multiplication"`

`"That is " color(blue)(1.1)/color(red)(1.2)=color(red)(n)/color(blue)(3.6)`

To solve, multiply the `color(red)"red terms"` and the `color(blue)" blue terms"` together and equate them.

`rArrcolor(red)(1.2n)=color(blue)(1.1)xxcolor(blue)(3.6)`

`rArr1.2n=3.96`

To solve for n, divide both sides by 1.2

`cancel(1.2 n)/cancel(1.2)=3.96/1.2`

`rArrn=3.3" is the solution"`
