Question

1 1/5 + 3/4 - (-3 3/5) - (-2 1/4)

Answer 1

Explanation:

`= 1 (1)/(5) + (3)/(4) - ( - 3 (3)/(5) ) - ( - 2 (1)/(4) )`

`= 1 (1)/(5) + (3)/(4) + 3 (3)/(5) + 2 (1)/(4)`

`= (1 + 3 + 2) + ( (1)/(5) + (3)/(4) + (3)/(5) + (1)/(4) )`

`= 6 + ( (4 + 15 + 12 + 5)/(20) )`

`= 6 + (36)/(20)`

`= 1 + 6 + (16)/(20)`

`= 7 + (4)/(5)`

`= 7 (4)/(5)`

Answer 2

The answer is 61/10

Explanation:

1 1/5 + 3/4 - (- 3 3/5) - (- 2 1/4)

1 × 5 + 1/5 + 3/4 - (- 3 × 5 + 3/5) - (- 2 × 4 + 1/4)

6/5 + 3/4 + 12/5 + 7/4

6/5 + 12/5 + 3/4 + 7/4

(6 + 12/5) + (3 + 7/4)

18/5 + 10/4

18/5 + 5/2

Now, Cross Multiply

18 × 2/5 × 2 + 5 × 5/2 × 5

36/10 + 25/10 = 61/10

Thus, The answer is 61/10
