Subtract 8 1/2 - 4 2/5?

Answer 1

41/10 or 4 1/10 which equals 4.1.

Answer 2

You need to find the common denominator between them that both #'s can be divided into. : The number on the bottom of the fraction. The demoninators in this problem are 2 and 5, what is common between them? 10.

Then take each denominator and divide it in. so. 10/2 is 5. 10/5 is 2. You then multiply that number by the top number to make it the top number in the fraction, keeping the new common denominator at the bottom.

So now you have 8 and 5/10 and 4 and 4/10. So. now, you solve it. The new problem is 8 5/10 - 4 4/10.

I hope you followed that. I think its right. I haven't had math in a long time but I am a college graduate so I'd like to think that I do remember something. haha. If I'm wrong, I apologize.

Answer 3

1) buy a calculator that can do fractions

or,

2) first, find the common demoninator:

8 1/2 = 8 5/10
4 2/5 = 4 4/10

then subtract:

8 5/10 - 4 4/10 = 4 1/10

Answer 4

first, find the common demoninator:

8 1/2 = 8 5/10
4 2/5 = 4 4/10

then subtract:

8 5/10 - 4 4/10 = 4 1/10

Answer 5

First make like fractions, common denominatr is 10, so 8 1/2 becomes 8 5/10 minus 4 2/5 which is now 4 4/10.
Answer is 4 1/10

Answer 6

4. 1

Answer 7

8 1/2 = [(8 x 2) + 1] / 2 = [ 16 + 1 ] / 2 = 17/2

4 2/5 = [(4 x 5) + 2] / 5 = [ 20 + 2 ] / 5 = 22/5

(8 1/2) - (4 2/5) = (17/2) - (22/5) = [ (17 x 5) - (22 x 2) ] / (2 x 5) = (85 - 44) / 10 = 41/10 = 4.1

:) easy ****

Answer 8

4 1/10 convert the fractions to a common denominator its easier to subtract

Answer 9

you want a basic denominator for this one. so, -a million/2 can change into -4/8 for our applications. now you've: -4/8 - (-5/8) 2 negatives make a large, so one can simplify to: -4/8 + 5/8 upload in the course of the numerators, to furnish us our answer it truly is: a million/8

Answer 10

4 1/10

Get common denominators..so it would be:

85/10 - 44/10

which equals = 41/10 --> reduce to 4 1/10
