Question

8/3 + 3/4 =

a) 1 4/7

b) 3 5/12

c) 11/12

d) 3 1/2

Answer 1

`3(5)/(12)`

Explanation:

When adding fractions, you always look for LCD.

(Least Common Denominator)

So since we have 3 and 4 as our denominators, find the LCD:

LCD of 3 and 4 is 12

Meaning the 12 is our denominator.

We can take out A. because it does not follow the denominator of 12.

Next, what you is multiply the numerator to like what you did with the denominators:

`(8 * 4)/(12)  + (3 * 3)/(12)`

`==> (32)/(12)  + (9)/(12)`

Add them together to get:

`(32+9)/(12)`

`==> (41)/(12)`

Simplify:

`3(5)/(12)`
