Answer 2

Answer:

2 53/180

Step-by-step explanation:

given : the length of the wooden piece = 85/9

length of first wooden block = 15/4

length of second wooden block = 17/5

find : length of remaining piece of wooden

solutions : 85/9 - (15/4 +17/5)

= 85/9 -(15 × 5/4 × 5 + 17 × 4/5)

= 85/9 - (75/20 + 68/20)

= 85/9 - 143/20

= 85 × 20/9 × 20 - 143 × 9/20 × 9

= 1700 /180 - 1287/180

= 413/180

= 2 53/180
