rachel wants to reduce the size of her photo. Which factor listed below would scale down the size of her picture the most?

A. 5/8
b. 11/16
c. 3/4
d. 8/5

trying to help my son with his math …have no idea about this.. could someone explain it to me?

The largest fraction scales it down the most.

We can eliminate 8/5 because that's more than 1.

Change all of the fractions to their equivalents with a common denominator of 16.

5/8 = 10/16
3/4 = 12/16

Which is the fraction with the highest numerator?

3/4 correct?

Right.

thank you very much , Have a great Hoilday

Thanks. And I hope you have a wonderful holiday, too.

If the largest fraction scales it down the most, wouldn't it be 3/2 which is 1 1/2?

Sure! I'll be happy to explain it to you.

To reduce the size of a photo, you need to scale it down. Scaling down means making the photo smaller. The factor you choose determines how much smaller the photo becomes.

In this case, the listed factors are fractions. When we scale down a photo, we multiply its dimensions by a fraction. The numerator of the fraction tells us how much we reduce the height, and the denominator tells us how much we reduce the width.

To find the factor that scales down the size of the photo the most, we need to find the fraction with the smallest value. The smaller the fraction, the more the photo will be reduced in size.

Let's compare the given fractions:

A. 5/8
B. 11/16
C. 3/4
D. 8/5

To compare fractions, we can convert them to decimals. Let's do that:

A. 5/8 = 0.625
B. 11/16 = 0.6875
C. 3/4 = 0.75
D. 8/5 = 1.6

Looking at the decimals, we can see that the smallest decimal value is for option A, 0.625. Therefore, option A (5/8) will scale down the size of Rachel's photo the most.

So the correct answer is option A (5/8).
