Beth's mother can sew 235 pairs of short pants in 6 days while Lourdes can sew 187 pairs in 8 days. How many more pairs of short pants can Beth's mother sew?

Correct result:

x =  15.917

Solution:

d1=235/6=2356≐39.1667 d2=186/8=934=23.25  x=d1−d2=39.1667−23.25=19112=15.917d_{1}=235/6=\dfrac{ 235 }{ 6 } \doteq 39.1667 \ \\ d_{2}=186/8=\dfrac{ 93 }{ 4 }=23.25 \ \\ \ \\ x=d_{1}-d_{2}=39.1667-23.25=\dfrac{ 191 }{ 12 }=15.917
