David received his allowance on Sunday. He spends 1/4 of his allowance on Monday and 2/3 of the remainder on Tuesday. What part of his allowance is left for the rest of the week?
(A) 1/3(B) 1/12(C) 1/4(D) 1/2(E) 4/7

Respuesta :

He spent 1/4 on Monday, so he had 3/4 left.

He then spent 2/3 of that, to find how much he spent you would multiply 3/4 by 2/3:

3/4 x 2/3 = 6/12 = 1/2

On Tuesday he spent 1/2 of his allowance.

So on Monday and Tuesday he spent 1/4 + 1/2 = 3/4 total.

He would have 1/4 of his allowance left.

The answer is C.
