Advertisements
Solution
Total quantity of juice = `5 1/2` litres
= `11/2` litres
Nazima gave to her friends = `2 3/4` litres
= `11/4` litres
∴ The required quantity of juice she is left with = `(11/2 - 11/4)` litres
= `((11 xx 2)/(2 xx 2) - 11/4)` litres ...[∵ L.C.M. of 2 and 4 is 4]
= `((22 - 11)/4)` litres
= `11/4` litres
= `2 3/4` litres
