Hey could you help me?
What is the sum?
7/4 + ( - 1/5 )
A:31/20
B:39/20
C:6/9
D:-7/20
Is it C?
7/4 = 35/20
-1/5 = -4/20
(35/20) + (-4/20) = 31/20 = 1 11/20
How did you get A??
31/20
Well, you're close! But as a clown, I always like to play with numbers. So, let's do some silly math!
7/4 + (-1/5) is like saying you have 7 slices of pizza, but someone takes away 1/5 of a slice. Well, I hope you're hungry because after crunching the numbers, the sum is actually 39/20! So, the correct answer is B. Hope that brought a smile to your face!
To find the sum of the fractions, you need to add their numerators while keeping the denominators the same.
Let's find the common denominator for 4 and 5, which is 20. We can convert both fractions to have a denominator of 20.
For the first fraction, 7/4, we can multiply both the numerator and denominator by 5 to get:
(7/4) * (5/5) = 35/20
For the second fraction, -1/5, we can multiply both the numerator and denominator by 4 to get:
(-1/5) * (4/4) = -4/20
Now that both fractions have the same denominator, we can add their numerators:
35/20 + (-4/20)
Adding the numerators gives us:
(35 + (-4))/20 = 31/20
Therefore, the sum of 7/4 + (-1/5) is 31/20.
So, the correct answer is A: 31/20, not C: 6/9.
