Am average 10 year old weights about 86 1/2 pounds and has muscles that weigh about 34 1/5.Find the difference between these two weights.

Subtract: 86.5 - 34.2 = ?

I don't know how too.

How did you get 35.2 ?

I mean 34

She got 34.2 because she changed 1/5 to a decimal. Then, she added 0.2 to 34 to get 34.2, which is the same thing as 34 1/5.

1/5 = 0.2

1/2 = 0.5

In order to do this, just divide the top and bottom. So, for 1/5, just divide 1 by 5 to get 0.2.

I hope this helps? :)

Oh ok thank you Brady.

Ms.sue I have another question.

You're welcome, Kaylyn. :)

Oops, I mean Kalyn. Also, sorry that I posted in a weird spot for my post before this one. I didn't see your last post.

What is your question, Kalyn?

And thanks for your explanation, Brady.

Would the answer be 52.3 and can it be simplfied

Yes, it's 52.3 and it's already simplified.

52.3 = 52 3/10

You're welcome Ms. Sue.

Kalyn, 52.3 can be simplified, by turning it into a mixed fraction. However, you can of course, leave it as 52.3.

The first thing you can do is to figure out the place value of the 3.

The 3 is in the tenths place, so moving the decimal to the right will get a 10. This should also get rid of the decimal.

With the 10, place it under the 523 with a fraction bar in between. This should be 523 / 10. So, the decimal now becomes a improper fraction at this point. However, you want a mixed fraction.

Since there are 52 tens in 520, this is now a whole number and goes outside the fraction. However, this leaves 3 leftover in the fraction, and this part becomes 3/10. So now, you have 52 3/10 as the final simplified answer.

I hope this helps! :)

P.S. Sorry for a later answer, I had to figure out how to explain the process better for in this post.

Or as Ms. Sue said, "52.3 = 52 3/10".

Sorry that I didn't see your post before me, Ms. Sue.
