7/3+(-3/8)
a) 65/24
b) 47/24
c) -4/5
d) -5/4
im really suck on this but i think its.. c?
7/3 + (-3/8) = 7/3-3/8 = 56/24-9/24 = 47/24.
thank you so much^
You are welcome.
To find the sum of fractions, you need to have a common denominator. In this case, the denominators are 3 and 8, so you need to find the least common multiple (LCM) of these two numbers, which is 24.
To convert 7/3 to have a denominator of 24, multiply both the numerator and denominator by 8: (7/3) * (8/8) = 56/24.
To convert -3/8 to have a denominator of 24, multiply both the numerator and denominator by 3: (-3/8) * (3/3) = -9/24.
Now that the fractions have a common denominator of 24, you can add them together:
56/24 + (-9/24) = 47/24.
Therefore, the correct answer is b) 47/24.
