1.) top row: 100 200 300 400 500 600. Bottom row: 5 10 15 20 25 30
2. Each ratio is just the top row divided by the bottom row. So the second thing in the ratio would be 200/10, the third one 300/15, etc. Each ratio is equal to 20.

Answer:

70% = $\frac{70}{100} = \frac{7}{10} = 0.7$

20% = $\frac{20}{100} = \frac{1}{5} = 0.2$

Step-by-step explanation:

We know that x% is represented by the fraction $\frac{x}{100}$ .

Now, in the first part, we are given two percentages 75% and 70%.

Now, 75% = $\frac{75}{100} = 0.75$

and 70% = $\frac{70}{100} = \frac{7}{10} = 0.7$

Therefore, the second option is correct.

Again, in the second part, we are given two percentages 20% and 25%.

Now, 20% = $\frac{20}{100} = \frac{1}{5} = 0.2$

and 25% = $\frac{25}{100} = \frac{1}{14} = 0.25$

Therefore, the third option is correct. (Answer)
