Question

(6 1/15+18/15)-(8-4 2/15)

Answer 1

6 19/15- 3 13/15= 3 2/5

Answer 2

1) 6 1/15 + 18/15= 15*6+1/15 + 18/15= 91/15 + 18/15= 91+18/15= 109/15= 7 4/15

2) 8 - 4 2/15= 8/1 - 4*15+2/15= 8/1 - 62/15= 15*8/15*1 - 1*62/15= 120/15 -65/15= 120-65/15= 58/15= 3 13/15

3) 7 4/15 - 3 13/15= 7*15+4/15 - 3*15+13/15= 109/15 - 58/15= 51/15= 17*3/5*3= 17/5= 3 2/5
