Question

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

Answer 1

Step-by-step explanation:

$= 1 \frac{1}{5} + \frac{3}{4} - ( - 3 \frac{3}{5} ) - ( - 2 \frac{1}{4} )$

$= 1 \frac{1}{5} + \frac{3}{4} + 3 \frac{3}{5} + 2 \frac{1}{4}$

$= (1 + 3 + 2) + ( \frac{1}{5} + \frac{3}{4} + \frac{3}{5} + \frac{1}{4} )$

$= 6 + ( \frac{4 + 15 + 12 + 5}{20} )$

$= 6 + \frac{36}{20}$

$= 1 + 6 + \frac{16}{20}$

$= 7 + \frac{4}{5}$

$= 7 \frac{4}{5}$

Answer 2

Answer:

The answer is 61/10

Step-by-step 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
