Length of string Karen's father earlier had = 18 3/8 m
This is a mixed fraction, converting it to normal fraction, we get
(18 x 8 + 3)/8 = 147/8 m
Length of string he gave to is friend = 10 5/9 m
This is a mixed fraction, converting it to normal fraction, we get
(10 x 9 + 5)/9 = 95/9 m
String left with him =
= 147/8 - 95/9
We can write this by taking LCM as 72, as
= 1323/72 - 760/72
= 563/72 m
Turning it into mixed fraction we write it as
(72 x 7 + 59)/72
= 7 59/72 m
Therefore, length of string left is 7 59/72 m.
