Question

Which ratio forms a proportion with 7/8
28/40 21/24 49/64

Answer 1

Divide 28 by 7 and that's 4. Divide 40 by 8 and that's 5. Therefore, the top and bottom resulting answers aren't the same.

Now divide 21 by 7 and that's 3. Divide 24 by 8 and that's 3. Therefore, this forms a proportion of 7/8.

Just for the heck of it, let's try the last one.

Divide 49 by 7 and that's 7. Divide 64 by 8 and that's 8. Therefore the tope and bottom resulting answers aren't the same and this can't be a proportion of 7/8.

You're welcome. I wish I could come back to math like this :-)

Answer 4

you just did

Answer 5

Really... I'm scared to move on

Answer 6

Don't be! Even though it's challenging, you have so many epiphanies. It's like your brain grows!

Answer 7

What you need to do is see how this math is applied. When you get into calculus (and I KNOW you'll take calculus), you'll see how it's applied in physics. Very fun stuff.
