Question

Later you have another chocolate bar. This time, after you give away 1/3 of the

bar, a friend breaks off 3/4 the remaining piece. What part of the original
chocolate bar do you have left?

Answer 1

chocolate bar - 1 (whole number)

Explanation:

`1 - (1)/(3) \\ > (3)/(3) - (1)/(3) = (2)/(3)`

`(2)/(3) - (3)/(4) \\ > (2 * 4)/(3 * 4) - (3 * 3)/(4 * 3) \\ \\ \\ > (8)/(12) - (9)/(12)`

so I switch it become

`(9)/(12) - (8)/(12) = (1)/(12)`
