Question

Also help me with this too

Answer 1

x=612

Explanation:

In this type of equation, you can easily turn it into an easier form for finding x.

`(x)/(900) =(68)/(100) \\`

In my school, this was taught as the cross technique. The numerator of one element is multiplied by the denominator of the other element, making the equation easier to find an unknown.

for finding x:

100x=68·900=61200

x=
`(61200)/(100)`

x=612
