€40 = 1/6 of the remainder.
Therefore the total remainder is €40 x 6 = €240

Three quarter of her wages = €240

Therefore to get the full amount you need to get 1 quarter, and then multiply it by 4 to get 4 quarters [the total].

So, €240 ÷ 3 = €80

€80 x 4 = €320

Her weekly wage is €320.

aaahhh fractions..... just begen with taking 1 as the wage nd take a quarter away nd so forth.. piece of pie.. 320 right?

anyways... im not botherd with this.. just use logic nd stuff..

... do u call this gloating btw? (not you )

I would just solve it by easy equation.

x - (1/4)*x - (3/4)*(5/6)*x = 40

(24/24)*x - (6/24)*x - (15/24)*x = 40

(3/24)*x = 40

1/8 * x = 40

x = 40 * 8

x = 320

Thats a bit more mathematical way.

you could of been mathematical, and kept it simple


3/4*1/6=40
1/8=40
total = 320
