Answer:
If Ali used 8 1/2 m of the thread..
12 1/4m
If Ali used 7 3/8 m more..
4 7/8 m
Step-by-step explanation:
GIVEN:
Total length = 20 3/4
Length of thread Ali used = 81/2 Length of thread left = ?
Length of thread left
= 20 3/4 - 8 1/2
= 83/4 - 17/2
= (83×1) - (17×2)/4
{After LCM}
= 83-34/4
= 49/4
= 12 1/4 m
Length of thread left after using 7 3/8 m
more = ?
Length of thread left after using 7 3/8 m more
= 12 1/4 - 7 3/8
= 49/4 - 59/8
= (49×2)-(59×1)/8
= 98-59/8
= 39/8
{After LCM}
= 4 7/8 m
