Can someone please help me with this math problem. My teacher is looking for me to show my work, but I don't how to solve the problem to show my work. Please help!!! The problem is 2 1/2 + 3 1/4 + 3 5/8. Thank you for your help.
2 1/2 + 3 1/4 + 3 5/8
First you need to find the common denominator -- which is 8.
Then convert each fraction to the common denominator.
2 1/2 = 2 4/8
3 1/4 = 3 2/8
Add:
2 4/8 + 3 2/8 + 3 5/8
What do you get?
Hi Sue,
Thanks for responding so promptly. After adding the problem I got 8 11/8 but my answer isn't one of the multiple choices. What am I doing wrong now? The multiple choices are 10 3/8, 9 3/8, 7 3/8 or 8 3/8. Thanks again for your help.
Your answer of 8 11/8 is right. But you need to reduce or simplify it.
8 11/8 = 9 3/8
Sue, thank you so very much. I now will practice this problem for future references. Thanks again.
You're welcome, Adore.
what precent of 3.5 is 7.2? show your work please.
Of course, I'll be happy to help you solve the math problem and show your work!
To add mixed numbers like 2 1/2, 3 1/4, and 3 5/8, we'll need to follow these steps:
Step 1: Convert the mixed numbers to improper fractions.
Step 2: Find a common denominator for all three fractions.
Step 3: Add the fractions together.
Step 4: Simplify the fraction (if needed) and convert it back to a mixed number.
Let's start with Step 1. To convert a mixed number to an improper fraction, you multiply the whole number by the denominator and add the numerator. For example:
2 1/2 = (2 x 2) + 1 = 4 + 1 = 5/2
3 1/4 = (3 x 4) + 1 = 12 + 1 = 13/4
3 5/8 = (3 x 8) + 5 = 24 + 5 = 29/8
Now, let's move on to Step 2. To find a common denominator, we need to find the least common multiple (LCM) of the denominators 2, 4, and 8. In this case, the LCM is 8.
Therefore, we need to rewrite the fractions with a common denominator of 8:
5/2 = (5/2) x (4/4) = 20/8
13/4 = (13/4) x (2/2) = 26/8
29/8 (already in terms of 8)
Now, Step 3. We can add the fractions together:
(20/8) + (26/8) + (29/8) = 20 + 26 + 29 / 8 = 75/8
Finally, in Step 4, we simplify the fraction. Since 75/8 cannot be reduced any further, we convert it back to a mixed number by dividing the numerator (75) by the denominator (8):
75 รท 8 = 9 remainder 3
The mixed number representation of 75/8 is 9 3/8.
Therefore, the solution to the problem 2 1/2 + 3 1/4 + 3 5/8 = 9 3/8.
I hope this explanation helps you understand the process of solving the problem and showing your work. Let me know if you have any further questions!
