Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$Work\ out1\cdot8\div0.3-4\cdot02; \times2+6\cdot5$$

Answer

26.666666666667*Wo*r*k*o*u*t-4*02;*2+30

Solution


Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\begin{aligned}&\frac{Workout\times 1\times 8}{0.3}-4\times 02\\&\times 2+6\times 5\end{aligned}\]
Simplify  \(Workout\times 1\times 8\)  to  \(8rkoutWo\).
\[\begin{aligned}&\frac{8rkoutWo}{0.3}-4\times 02\\&\times 2+6\times 5\end{aligned}\]
Regroup terms.
\[\begin{aligned}&\frac{8Workout}{0.3}-4\times 02\\&\times 2+6\times 5\end{aligned}\]
Simplify  \(\frac{8Workout}{0.3}\)  to  \(26.666667Workout\).
\[\begin{aligned}&26.666667Workout-4\times 02\\&\times 2+6\times 5\end{aligned}\]
Simplify  \(6\times 5\)  to  \(30\).
\[\begin{aligned}&26.666667Workout-4\times 02\\&\times 2+30\end{aligned}\]
