Answer 1

Answer:

3/7/20

Step-by-step explanation:

is 4/1/4 m was used in first shirt and 3/2/5 was used second then it means rest was used in third shirt

so to get the required no. you should add 4/1/4 and 3/2/5 and subtract by 10

4/1/4+3/2/5=17/4+17/5(take out the LCM) =85/20+68/20=153/20

153/20-10=200/20-153/20=47/20(now change it in mixed fraction)=2/7/20
