To add or subtract fractions, we first need to find a common denominator.
1) 5/13 + 4/1(5 + 4) / 13 = 9 / 13
2) 9/13 + (5/13 + 49/60To find a common denominator for 9/13, 5/13, and 49/60, we need to find the least common multiple of 13 and 60, which is 780.
9/13 = 468/785/13 = 300/7849/60 = 637/780
So, the calculation becomes468/780 + 300/780 + 637/78= (468 + 300 + 637) / 78= 1405 / 780
Therefore, the final result is 1405/780, which can be further simplified if needed.
To add or subtract fractions, we first need to find a common denominator.
1) 5/13 + 4/1
(5 + 4) / 13 = 9 / 13
2) 9/13 + (5/13 + 49/60
To find a common denominator for 9/13, 5/13, and 49/60, we need to find the least common multiple of 13 and 60, which is 780.
9/13 = 468/78
5/13 = 300/78
49/60 = 637/780
So, the calculation becomes
468/780 + 300/780 + 637/78
= (468 + 300 + 637) / 78
= 1405 / 780
Therefore, the final result is 1405/780, which can be further simplified if needed.
