Answer 2

1,1/4=5

To solve this equation, we need to convert the mixed number 1 1/4 into an improper fraction.

1 1/4 can be written as (4 * 1 + 1)/4 = 5/4.

Now, we can divide 5/4 by 1/4:

(5/4) / (1/4) = (5/4) * (4/1) = 5.

Therefore, 1 1/4 divided by 1/4 equals 5.

+1/8:3

To solve this equation, we need to divide 1/8 by 3.

1/8 divided by 3 can be written as (1/8) / (3/1) = (1/8) * (1/3) = 1/24.

Therefore, 1/8 divided by 3 equals 1/24.

+3/7

There is no operation specified for 3/7. If you meant to add it to the previous results, we can add 3/7 to 5 and 1/24.

5 + 1/24 + 3/7

To add these fractions, we need to find a common denominator.

The common denominator for 24 and 7 is 168.

Converting 1/24 and 3/7 to have a denominator of 168:

1/24 = (1/24) * (7/7) = 7/168 3/7 = (3/7) * (24/24) = 72/168

Now, we can add the fractions:

5 + 7/168 + 72/168 = (5 * 168 + 7 + 72) / 168 = (840 + 7 + 72) / 168 = 919/168.

Therefore, the result of adding 3/7 to the previous results is 919/168.
