Which is a greater number

-9/10 or -7/8

-7/8 = -0.875

-9/10 = -0.9

-7/8 is greater because it is negative and the number is closer to zero.

The greater number is -7/8.

Step-by-step explanation:

Let's make the denominator the same!

We can multiply the bottoms by an amount to get the same denominator.

10 * 8 = 80, and so is 8 * 10 so we have a denominator of 80 for each fraction. We have to do this for the top now. -9 * 8 = -72 and -7 * 10 = -70.

We have fractions of -72/80 and -70/80

If we are looking for the GREATEST number, we would normally look for the biggest looking number. This would be "72" HOWEVER since this is negative, we are actually going farther from zero and getting smaller so -70 would be the greatest number technically.

This means the fraction -7/8 is greater. Hope this helps!
