Question

1/3 + 1/4 and the the sinplest form

Answer 1

The least common multiple between 3 and 4 is 12, so we can use this fact to rewrite both 1/3 and 1/4 in 12ths:


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

We're left with an answer of 7/12, which can't be reduced.
