Sam has [tex]\frac{3}{4}[/tex] kg of toffees. If he gives [tex]\frac{3}{8}[/tex] kg to Mike, how much will he have left?
Answer (3)
Number toffees Sam had = 3/4 kg. Number of toffees he gave to Mike = 3/8 kg. Toffees left = 3/4 - 3/8 = 0.75 - 0.375 = 0.375 kg. ***Number of toffees he had left = 3/8 kg. ***
4 3 k g − 8 3 k g L C D ( 4 3 ; 8 3 ) l i s t t h e m u lt i pl es o f 4 : 0 ; 4 ; 8 ; 12 ; ... L C D ( 4 3 ; 8 3 ) = 8 4 3 = 4 × 2 3 × 2 = 8 6 4 3 k g − 8 3 k g = 8 6 k g − 8 3 k g = 8 6 − 3 k g = 8 3 k g A n s w er : M ik e ha d l e f t 8 3 k g o f t o ff ees .
After giving 8 3 kg of toffees to Mike, Sam will have 8 3 kg of toffees left. The calculation involved finding a common denominator to subtract the fractions. Thus, Sam's remaining amount of toffees is 8 3 kg.
