Question

3 3/4 + 5/12
help me plz lol​

Answer 1

4
`(1)/(6)`

Explanation:

When adding fractions, you want to make the denominators of the fraction the same. To do this, we can multiply both the numerator and denominator of 3/4 by 3. When changing either a denominator or numerator in a fraction, you must do the same thing to the numerator as the denominator.

Now we have
`(3\cdot3)/(4\cdot3) = (9)/(12)`. To add 9/12 and 5/12, we keep the denominator the same, and add the numerators, getting
`(9+5)/(12) =(14)/(12)`. This is greater than 1, so we can take 12/12 from 14/12, and make it
`1 (2)/(12)`. If we then add 3, we get
`4 (2)/(12)`, which simplifies to
`4 (1)/(6)`
