$40 \div \dfrac{3}{2} + 10 \ne 90$ now, $40 \div \dfrac{1}{2} + 10 = 90$

You mean it is translated as "divide 40 by one, then by half, and add 10"?

That is what is suggested. Kiwis, where did you get the "90" from? 40 divided by "one and a half" is 80/3= "26 and 2/3". Then "add 10" is "36 and 2/3".

Kiwis seems to post these "confusing" problems fairly often; wonder if he's doing it on purpose...

Or the question wasn't in English and it's just lost in translation. Didn't I experience similar case before?
