Question

1. Subtract the first original number from the 2nd in each of the following.
1. 3/8, 5/8 2.-7/9, 4/9 3.-2/11, -9/11 4. 11/13, -4/13​

Answer 1

Ans: 1. -1/4 2. -1.222... 3. 0.636... 4. 1.153

Explanation:

1. 3/8 - 5/8

Here, Denominator is same. So, We can write as

= (3 - 5) / 8

= - 2/8

= -1/4

or -0.25

2. - 7/9 - 4/9

Here, Denominator is same. So, We can write as

= (- 7 - 4) / 9

= -11/9

or -1.222...

3. -2/11 - (-9/11)

or -2/11 +9/11

Here, Denominator is same. So, We can write as

= (-2+9) / 11

= 7/11

or 0.636...

4. 11/13 - (- 4/13)

or 11/13 + 4/13

Here, Denominator is same. So, We can write as

= (11+4) / 13

= 15/13

or 1.153
