EXAMPLE 1:
Mashitah has RM 4 530 in savings. His father distributed RM 150 equally to Mashitah and his 2 younger siblings. How much money does Mashitah have now?
SOLUTION:
Mashitah's savings: RM 4 530 Money given by Mashitah's father: RM 150 divide 3 Mashitah's total money: RM \(\Box\)
Mathematic Equation: \(4\,530+(150\div3)=\Box\)
Solve the division first.
\(150\div3=50\)
Substitute into the equation and solve.
\(4\,530+(50)=4\,580\)
Therefore, Mashitah's total money is RM 4 580.
EXAMPLE 2:
A cement company has sent 4 trucks full of cement packages to a construction site. Each truck carries 45 packages of cement. On the way, 8 cement packages were torn. How many packages of cement are still good?
Number of trucks: 4 trucks Number of cement packages in 1 truck: 45 packages Number of torn packages: 8 packages Number of good packages = \(\Box\) packages
Mathematic Equation: \(4\times45-8=\Box\)
Solve the multiplication first.
\(\begin{array}{lr} &45\\ \times&4\\ \hline&180\\ \hline \end{array}\)
\(180-8=172\)
Therefore, 172 packages are still good.
