Answer:

1. R= 16.67%

2. P= 48.3

3. P= 6.6

4. R= 78.57%

Step-by-step explanation:

Use the Techan's Triangle as a formula

(1 and 4) Rate=divide the percentage by base and multiply by 100

1. 2÷12=0.1666...×100=16.666...%

Estimated=16.67%

4. 22÷28=0.785714286×100=78.5714286%

Estimated=78.57%

(2 and 3) Percentage=multiply base by rate (in decimal form)

2. 23%=0.23

210×0.23=48.3

3. 22%=0.22

28×0.22=6.6
