**Question 1**

Find X in 11 2/3 + 9 3/4 - 11 2/5 = X

a) 10 1/60 b) 9 3/4 c) 11 3/4 d) none of these

**Answer :** a) 10 1/60

Solution :

By the above note, we can re write the given eqn as

X = 11 2/3 + 9 3/4 - 11 2/5

= 11 + 2/3 + 9 + 3/4 - 11 - 2/5

= (11+9-11) + 2/3 + 3/4 - 2/5

= 9 + (40 + 45 - 24)/60

= 9 + 61/60

= 9 + 1 + 1/60

= 10 + 1/60

X = 10 1/60

Hence, the answer is 10 1/60.

**Question 2**

The value of X in 1 2/17 - 4 1/19 + 3 1/34 = X is:

a) 5/43 b) 120/34 c) 61/646 c) 120/646

**Answer :** c) 61/646

Solution :

Given that X = 1 2/17 - 4 1/19 + 3 1/34

X = 1 + 2/17 - 4 - 1/19 + 3 + 1/34

= (1 - 4 + 3) + 2/17 - 1/19 + 1/34

= 2/17 + 1/34 - 1/19

= 5/34 - 1/19

= (95 - 34) / (34x19)

= 61/646

Hence, the answer is 61/646

**Question 3**

Find X in the equation 8 1/3 + 1 1/9 + X = 2 2/3

a) 5 8/9 b) 6 7/9 c) 6 4/9 d) 5 3/9

**Answer :** b) 6 7/9

Solution:

Given that 8 1/3 + 1 1/9 - X = 2 2/3

X = 8 1/3 + 1 1/9 - 2 2/3

= 8 + 1/3 + 1 + 1/9 - 2 - 2/3

= 8 + 1 - 2 + 1/3 + 1/9 - 2/3

= 7 + 1/9 - 1/3

= 7 - 2/9 = 61/9

= 6 + 7/9

Hence the answer is 6 7/9

**Question 4**

Find X in the equation 7 2/15 + X - 6 4/45 = 13 2/9

a) 12 8/45 b) 7/45 c) 12 1/45 d) 6 4/9

**Answer :** a)12 8/45

Solution :

Given that 7 2/15 + X - 6 4/45 = 13 2/9

X = 13 2/9 - 7 2/15 + 6 4/45

= 13 + 2/9 - 7 - 2/15 + 6 + 4/45

= (13 - 7 + 6) + 2/9 - 2/15 + 4/45

= 12 + (10 - 6 + 4)/45

= 12 + 8/45

= 12 8/45

Hence the answer is 12 8/45.
