Answer 2

Subtraction Operations:

1) 1) 7/15 - 3/25:

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 75.

7/15 can be written as 35/75, and 3/25 can be written as 9/75.

Subtracting these fractions, we get:

35/75 - 9/75 = 26/75.

So, the result of 7/15 - 3/25 is 26/75.

2) 2) 3/4 - 1/6:

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 12.

3/4 can be written as 9/12, and 1/6 can be written as 2/12.

Subtracting these fractions, we get:

9/12 - 2/12 = 7/12.

So, the result of 3/4 - 1/6 is 7/12.

3) 3) 7/8 - 5/12:

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 24.

7/8 can be written as 21/24, and 5/12 can be written as 10/24.

Subtracting these fractions, we get:

21/24 - 10/24 = 11/24.

So, the result of 7/8 - 5/12 is 11/24.

4) 4) 11/40 - 9/50:

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 200.

11/40 can be written as 55/200, and 9/50 can be written as 18/200.

Subtracting these fractions, we get:

55/200 - 18/200 = 37/200.

So, the result of 11/40 - 9/50 is 37/200.

5) 5) 11/18 - 7/15:

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 90.

11/18 can be written as 55/90, and 7/15 can be written as 42/90.

Subtracting these fractions, we get:

55/90 - 42/90 = 13/90.

So, the result of 11/18 - 7/15 is 13/90.

6) 6) 29/42 - 17/63:

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 126.

29/42 can be written as 61/126, and 17/63 can be written as 34/126.

Subtracting these fractions, we get:

61/126 - 34/126 = 27/126.

Simplifying the fraction, we get:

27/126 = 3/14.

So, the result of 29/42 - 17/63 is 3/14.

7) 7) 14/15 - 5/9:

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 45.

14/15 can be written as 42/45, and 5/9 can be written as 25/45.

Subtracting these fractions, we get:

42/45 - 25/45 = 17/45.

So, the result of 14/15 - 5/9 is 17/45.

8) 8) 11/16 - 7/8 - 5/12:

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 48.

11/16 can be written as 33/48, 7/8 can be written as 42/48, and 5/12 can be written as 20/48.

Subtracting these fractions, we get:

33/48 - 42/48 - 20/48 = -29/48.

So, the result of 11/16 - 7/8 - 5/12 is -29/48.

9) 9) 7/10 - 4/15; 11/17 - 21/44 - 23/55:

To subtract fractions, we need to have a common denominator. In this case, the common denominator for both operations is 330.

For the first operation, 7/10 can be written as 231/330, and 4/15 can be written as 88/330.

Subtracting these fractions, we get:

231/330 - 88/330 = 143/330.

For the second operation, 11/17 can be written as 220/330, 21/44 can be written as 157.5/330, and 23/55 can be written as 138/330.

Subtracting these fractions, we get:

220/330 - 157.5/330 - 138/330 = -75.5/330.

So, the result of 7/10 - 4/15 is 143/330, and the result of 11/17 - 21/44 - 23/55 is -75.5/330.
