Question

Judy spent 1/3 of her money on clothes and 1/4 of her money on books. What part of her money was spent?

Answer 1

7/12 of her money was spent.

Explanation:

That is the sum of the 2 fractions:

1/3 + 1/4 LCM of 3 and 4 is 12 so we have:

4/12 + 3/12

= 7/12.

Answer 2

Explanation:

Part of the money spent = Part of money spent on clothes + part of money spent on books

`=(1)/(3)+(1)/(4)\\\\=(1*4)/(3*4)+(1*3)/(4*3)\\\\=(4)/(12)+(3)/(12)\\\\=(4+3)/(12)\\\\=(7)/(12)`

7/12 part of her money was spent
