Answer 3

To subtract mixed numbers, you'll need to convert them to improper fractions and then perform the subtraction. Let's start with the first subtraction:

11 4/13 - 2 9/13

To convert the mixed numbers to improper fractions, you multiply the whole number by the denominator of the fraction and then add the numerator. The result becomes the new numerator, and the denominator remains the same.

For 11 4/13: 11 * 13 + 4 = 143 + 4 = 147 So, 11 4/13 can be written as the improper fraction 147/13.

For 2 9/13: 2 * 13 + 9 = 26 + 9 = 35 So, 2 9/13 can be written as the improper fraction 35/13.

Now, subtract the fractions:

147/13 - 35/13 = (147 - 35)/13 = 112/13

To convert the improper fraction back to a mixed number, divide the numerator by the denominator:

112 ÷ 13 = 8 with a remainder of 8

So, the result is 8 8/13.

Now, let's move on to the second subtraction:

7 11/22 - 5 17/22

Converting to improper fractions:

For 7 11/22: 7 * 22 + 11 = 154 + 11 = 165 So, 7 11/22 can be written as the improper fraction 165/22.

For 5 17/22: 5 * 22 + 17 = 110 + 17 = 127 So, 5 17/22 can be written as the improper fraction 127/22.

Subtract the fractions:

165/22 - 127/22 = (165 - 127)/22 = 38/22

Simplify the fraction, if possible:

38/22 can be reduced by dividing both the numerator and denominator by their greatest common divisor, which is 2:

38 ÷ 2 = 19 22 ÷ 2 = 11

So, the simplified fraction is 19/11.

To convert the improper fraction back to a mixed number, divide the numerator by the denominator:

19 ÷ 11 = 1 with a remainder of 8

So, the result is 1 8/11.

Therefore, the calculations are:

11 4/13 - 2 9/13 = 8 8/13 7 11/22 - 5 17/22 = 1 8/11
