I'm not understanding this problem. Write the rate in lowest terms. A printer can print 3 pages in 12 seconds. I need somebody to help me with this question.

Cora -- don't you think it's time for you to study your book and try to answer these questions yourself?

I'll be glad to check your answer.

I study this answer in the book, Determine whether y=15 is a solution to the proportion. To 14.2=7.1 over 29=y and the question was yes or no, and I say yes this problem. Can you see if its right or wrong please.

Your problem doesn't make any sense.

Is this what you mean?

14.2/7.1 = 29/y

If so, y does not equal 15.

To write the rate in lowest terms, we first need to find the ratio between the number of pages printed and the time taken. In this case, the printer can print 3 pages in 12 seconds.

To find the rate, we divide the number of pages by the time taken:
Rate = Number of pages / Time taken

In this case, the number of pages is 3 and the time taken is 12 seconds. So the rate is:

Rate = 3 pages / 12 seconds

To simplify the rate, we can divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 3 and 12 is 3.

Dividing both the numerator and the denominator by 3, we get:

Rate = (3/3) pages / (12/3) seconds
= 1 page / 4 seconds

So, the rate at which the printer prints pages is 1 page every 4 seconds.
