ms.sue answer my questions 9 and 7/10 - 5 and 3/4
First, what is the common denominator for 7/10 and 3/4?
After you post that answer, I'll help you from there.
29/20
Yes. 20 is the common denominator.
7/10 = 14/20
3/4 = 15/20
You need to subtract 5 15/20 from 9 14/20.
We need to make the top fraction larger. So we to subtract 1 from the whole number and add 20/20 to the fraction.
9 14/20 = 8 34/20
8 34/20 - 5 15/20 = 3 19/20
To answer the question, you need to subtract the second number from the first number. Here's how you can do it:
1. Convert the mixed numbers to improper fractions:
- 9 = 9/1
- 7/10 = 7/10
- 5 = 5/1
- 3/4 = 3/4
2. Find a common denominator: Since the denominators are 1, 10, and 4, the least common multiple is 20. So, we need to rewrite the fractions with a denominator of 20:
- 9/1 becomes 9/1 * 20/20 = 180/20
- 7/10 becomes 7/10 * 2/2 = 14/20
- 5/1 becomes 5/1 * 20/20 = 100/20
- 3/4 remains the same (since 4 is already the denominator we need)
3. Subtract the fractions:
- (180/20) - (14/20) = (180 - 14) / 20 = 166/20
4. Simplify the result, if needed:
- The fraction 166/20 can be simplified by finding the greatest common divisor (GCD) of the numerator and denominator. In this case, the GCD is 2. Dividing both the numerator and denominator by 2 gives us 83/10.
Thus, the answer to the question is 83/10 or 8 and 3/10.
