$\huge\color{pink}\boxed{\colorbox{Black}{❥Answer}}$

Total length of the cloth = 12m

length of cloth used in curtains = 1l37/am

= 34/9m

length of the cloth used in bed sheets = 24/7m = 18/7m

total length of cloth used = 34/9 + 18/7

LCM of 9,7 = 63

34×7/8×7=238/63

18×9/7×9/16/63

18×9/7×9=162/63

238/63 1-1 62/63

= 400/63

cloth remaining = 12/1 = 400/63

LCM of 1,63 = 63

12×63/1×63=756/63

756/60-400/63

= 356/63m
