Answer 1

1-3/4=4/4-3/4=1/4
1-1/5 =5/5-1/5=4/5
1-2/5 =5/5-2/5=3/5
1-4/5 =5/5-4/5=1/5
1-7/10 =10/10-7/10=3/10
1-5/13 =13/13-5/13=8/13
1-11/25 =25/25-11/25=14/25
1-25/25=25/25-25/25=0

Calculating the Sum of Fractions

To solve the given math problem, we need to add the following fractions: 1. 1 - 3/4 2. 1 - 1/5 3. 1 - 2/5 4. 1 - 4/5 5. 1 - 7/10 6. 1 - 5/13 7. 1 - 11/25 8. 1 - 25/25

Let's calculate each of these step by step.

1. 1 - 3/4 - To subtract 3/4 from 1, we can convert 1 to have a denominator of 4: 4/4. - So, 1 - 3/4 = 4/4 - 3/4 = 1/4.

2. 1 - 1/5 - To subtract 1/5 from 1, we can convert 1 to have a denominator of 5: 5/5. - So, 1 - 1/5 = 5/5 - 1/5 = 4/5.

3. 1 - 2/5 - To subtract 2/5 from 1, we can convert 1 to have a denominator of 5: 5/5. - So, 1 - 2/5 = 5/5 - 2/5 = 3/5.

4. 1 - 4/5 - To subtract 4/5 from 1, we can convert 1 to have a denominator of 5: 5/5. - So, 1 - 4/5 = 5/5 - 4/5 = 1/5.

5. 1 - 7/10 - To subtract 7/10 from 1, we can convert 1 to have a denominator of 10: 10/10. - So, 1 - 7/10 = 10/10 - 7/10 = 3/10.

6. 1 - 5/13 - To subtract 5/13 from 1, we can convert 1 to have a denominator of 13: 13/13. - So, 1 - 5/13 = 13/13 - 5/13 = 8/13.

7. 1 - 11/25 - To subtract 11/25 from 1, we can convert 1 to have a denominator of 25: 25/25. - So, 1 - 11/25 = 25/25 - 11/25 = 14/25.

8. 1 - 25/25 - To subtract 25/25 from 1, we get 0.

Now, let's add all these results together: 1/4 + 4/5 + 3/5 + 1/5 + 3/10 + 8/13 + 14/25 + 0

Summing the Fractions

To find the sum of these fractions, we can add them together: 1/4 + 4/5 + 3/5 + 1/5 + 3/10 + 8/13 + 14/25 = 1.92

So, the sum of the given fractions is 1.92.
