Question

2. A family bought 4 2 by 5 m , 3 1 by 3 m and 2 1 by 10 ( mixed fraction ) of cloth for three dresses. If the cloth was
a 30 m cloth. find the length of cloth left in the roll?​

Answer 1

Answer:121/6 or 12 1/6m

Step-by-step explanation:

4 2/5+ 3 1/3+2 1/10+x=30

22(6)+10(10)+21(3)+30x=30(30) (taking LCM we get 30)

132+100+63+30x=900

30x=900-295

x=605/30=121/6=12 1/6
