Sam has 3/4 kg of toffees. If he gives 3/8 kg to Mike, how many will he have left?


Sagot :

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. 
[tex]\frac{3}{4}kg-\frac{3}{8}kg\\\\LCD(\frac{3}{4};\ \frac{3}{8})\\\\list\ the\ multiples\ of\ 4:\ 0;\ 4;\ \fbox8;\ 12;...\\\\LCD(\frac{3}{4};\ \frac{3}{8})=8\\\\\frac{3}{4}=\frac{3\times2}{4\times2}=\frac{6}{8}\\\\\frac{3}{4}kg-\frac{3}{8}kg=\frac{6}{8}kg-\frac{3}{8}kg=\frac{6-3}{8}kg=\frac{3}{8}kg\\\\Answer:Mike\ had\ left\ \frac{3}{8}kg\ of\ toffees.[/tex]
