Answer 1

We have to complete the statements:

1) 20% of 60 is 12

$\frac{20}{100}\cdot60=0.2\cdot60=12$

2) 50% of 90 is 45

$\frac{50}{100}\cdot90=0.5\cdot90=45$

3) 25% of 24 is 6

$\begin{gathered} \frac{25}{100}\cdot x=6 \\ 0.25\cdot x=6 \\ x=\frac{6}{0.25}=24 \end{gathered}$

4) 10% of 70 is 7

$\begin{gathered} 0.1\cdot x=7 \\ x=\frac{7}{0.1} \\ x=70 \end{gathered}$

5) 14% of 100 is 14

$\begin{gathered} \frac{\alpha}{100}\cdot100=14 \\ \alpha=14 \end{gathered}$

6) 30% of 70 is 21

$0.3\cdot70=21$
