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

babymother [125]

Step-by-step explanation:

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

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

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

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

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

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

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

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