Answer:
Exact form: 43/12
Mixed number form: 3 7/12
Step-by-step explanation:
Convert the mixed numbers to improper fractions, then find the LCD and combine.
2 3/4 is 11/4 because you do (a b/c) a×b+c=d so 2×4+3=11
You now have 5/6 + 11/4
You put them on the same base
(6×4=24)
(5×4=20)
(11×6=66)
You have
20/24+66/24=84/24
You put back in normal
84-72=12
(72because it’s the biggest multiple of 24 you can fit in 84)
You have 3 full (12×?=72)
So the answer is 3 and 12/24 or 3 and 1/2
You now have 5/6 + 11/4
You put them on the same base
(6×4=24)
(5×4=20)
(11×6=66)
You have
20/24+66/24=84/24
You put back in normal
84-72=12
(72because it’s the biggest multiple of 24 you can fit in 84)
You have 3 full (12×?=72)
So the answer is 3 and 12/24 or 3 and 1/2
