What is the sum? (1 point) 7 thirds + - 3 eigths

Answer 1

To add 7 thirds and -3 eighths, we need to find a common denominator. The least common multiple of 3 and 8 is 24. Thus, we can convert 7 thirds to eighths by multiplying the numerator and denominator by 8 and -3 eighths to thirds by multiplying the numerator and denominator by 3:

7 thirds = (7/3) * (8/8) = 56/24
-3 eighths = (-3/8) * (3/3) = -9/24

Now, we can add the fractions together:

56/24 + (-9/24) = (56 - 9) / 24 = 47/24

So, the sum is 47/24.
