How to solve fractions​

Answer 1

Answer:

The key is finding a common # on the bottom (aka: a common 'denominator')

once you do this, you can easily add and subtract them!

Step-by-step explanation:

EX:

1/2 + 2/3 = ?

*EASIEST TRICK!!*

take your 2nd denominator: (3) and multiply it by the entire (1st fraction): 1/2

(when we MULTIPLY fractions, it is easy as pie, we can just multiply across the top and across the bottom) in this case, we will multiply both top and bottom by the 2nd denominator (3)

(1 x 3)/(2 x 3) = 3/6 (3/6 is another way of saying 1/2, so we're good!)

now take the 1st denominator (2), and multiply the entire 2nd fraction by that:

(2 x 2)/(3 x 2) = 4/6

now we have 6 on the bottom of both! time for the magic:

3/6 + 4/6 = 7/6

but wait! (that means we have 7 slices of a 6-piece pie! ...so we actually have, 1 full (6-piece pie) and 1 slice leftover! (awww yeeea)

so, 7/6 --> 1 (full pie) 1/6 (leftover!)

now to put it all back together:

1/2 + 2/3 = 1 & 1/6
