Answer 2

The value of x in 19÷25 = x ÷ 100 is 76

Solution:

From question, given that 19÷25 = x ÷ 100

We have to divide 19 by 25 and x by 100.So we get,

`(19)/(25)=(x)/(100)`

If we take 100 to the left hand side (L.H.S), it gets multiplied with left hand side equation. Hence we rewrite the equation as

`(19)/(25) * 100=x`

By cancelling 100 by 25 we get 4. Since
`25 * 4 = 100`

`19 * 4 = x`

76 =x

Therefore the value of x in 19÷25 = x ÷ 100 is 76
