Question

If there are $0.90 (US) to €1.00 how many euro would u get for $9.00 (US) ?

Answer 1

wouldn't the answer be 10 euros
$.90x10 = $9
1x10 = 10

Answer 2

`(.9)/(1) = (9)/(x)` Solve for x.

.9x=9*1 Divide both sides by .9

x=
`(9)/(.9)`=10

You would get 10.00 euros.

You can also think of it in this way, that you just move the decimal point over one to the left to get 10.
