After doing an experiment you learn that 70 percent of the carrot seeds from Company A germinated within 10 days, while only 50 percent of the seeds from company B germinated within 10 days. What was the comparative germination ratio?

looks like a simple 7:5 ratio to me

That's what i thought but the answer in the back of the book said 1:14. Unless there was a missing decimal point and it was 1:1.4.

huh

7/5=1.4/1
Would that be right?

To calculate the comparative germination ratio between the seeds from Company A and Company B, you need to compare the germination rates of both companies.

The germination rate for Company A is given as 70 percent, while the germination rate for Company B is given as 50 percent.

To find the comparative germination ratio, you need to express the germination rates as a ratio. In this case, you'll use the number of germinated seeds as the ratio.

Let's take a sample size of 100 seeds for each company to keep it consistent:

For Company A:
Germinated seeds = 70% of 100 = 70 seeds

For Company B:
Germinated seeds = 50% of 100 = 50 seeds

Now, you can express the germination rates as a ratio:

Company A: Company B = 70:50

To simplify the ratio, you can divide both sides by the greatest common divisor (GCD) of 70 and 50, which is 10:

Company A: Company B = 7:5

Therefore, the comparative germination ratio between Company A and Company B is 7:5.
