Final answer:

The completed statements are as follows:

1. 20% of 60 is 12.

2. 50% of 90 is 45.

3. 25% of 24 is 6.

4. 10% of 70 is 7.

5. 300% of 70 is 210.

Step-by-step explanation:

To find 20% of 60, you multiply 60 by 0.20, resulting in 12. For the second statement, calculating 50% of 90 involves multiplying 90 by 0.50, yielding 45. Moving on to the third statement, to determine 25% of an unknown value represented by "x," you set up the equation 0.25 * x = 6, and solving for x gives x = 24. For the fourth statement, finding 10% of an unknown value represented by "y" involves solving the equation 0.10 * y = 7, which results in y = 70. Lastly, calculating 300% of 70 is equivalent to multiplying 70 by 3, resulting in 210.

In summary, the completed statements are:

1. 20% of 60 is 12.

2. 50% of 90 is 45.

3. 25% of 24 is 6.

4. 10% of 70 is 7.

5. 300% of 70 is 210.

We have to complete the statements:

1) 20% of 60 is 12


(20)/(100)\cdot60=0.2\cdot60=12

2) 50% of 90 is 45


(50)/(100)\cdot90=0.5\cdot90=45

3) 25% of 24 is 6


\begin{gathered} (25)/(100)\cdot x=6 \\ 0.25\cdot x=6 \\ x=(6)/(0.25)=24 \end{gathered}

4) 10% of 70 is 7


\begin{gathered} 0.1\cdot x=7 \\ x=(7)/(0.1) \\ x=70 \end{gathered}

5) 14% of 100 is 14


\begin{gathered} (\alpha)/(100)\cdot100=14 \\ \alpha=14 \end{gathered}

6) 30% of 70 is 21


0.3\cdot70=21
