Answer:
3. 1 1/24
5. 5/7
6. 13/18
Step-by-step explanation:
3. We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.
Now we multiply 4 by 8, and get 32, then we multiply 6 by 8 and get 48.
Now for the second term. You multiply 3 by 6, and get 18, then multiply 6 by 8 and get 48.
fraction: 32/48 + 18/48
Since our denominators match, we can add the numerators.
32 + 18 = 50
fraction= 50/48 lowest term: 25/24 or 1 1/24
5. We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.
Now we multiply 8 by 7 and get 56, then we multiply 14 by 7 and get 98.
Now for the second term. You multiply 2 by 14 and get 28, then we multiply 7 by 14 and get 98.
fraction: 56/98 + 14/98= 70/98
and the we simplify it to its lowest term.
Answer: 5/7
6. We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.
Now we multiply 2 by 12, and get 24, then we multiply 9 by 12 and get 108.
Now for the second term. You multiply 6 by 9, and get 54, then multiply 9 by 12 and get 108.
fraction: 24/108 + 54/108
Since our denominators match, we can add the numerators.
24 + 54 = 78
fraction: 78/108
then we simplify it 13/18
