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? :)
