I need help on this algebra question . please give me a way to do it is well. Thank you?

Question

If a/b = 5/10 .
Find a-b / b

Answer 1

Should there be brackets around the 2nd expression, ie:
(a - b)/b ?

If so then subtract b/b from both sides of the first expression:
a/b - b/b = 5/10 - b/b

Because b/b = 1 the right side becomes completely known. The left side becomes the expression you want ((a - b)/b):
(a - b)/b = 1/2 - 1
(a - b)/b = -1/2

Answer 2

If a/b = 5/10, then (a - b) /b = (5 - 10) /10 = -5/10 or -1/2

Answer 3

a-b/b = a/b - b/b = a/b - 1, so = 5/10 -1 = -5/10 = -1/2

Answer 4

Hey there!

Decompose the fraction (a-b)/b. When you decompose the fraction, the partial fractions will be a/b-b/b or a/b-1. Now, since a/b=5/10, substitute 5/10 for a/b, where the problem would be 5/10-1.

Rewrite 5/10 as 1/2. The problem would now be 1/2-1.

So, what's the answer?

Find the least common denominator on both fractions, which is 2.

So the answer would look like this.

1/2-1 -->
1/2-2/2 -->
(1-2)/2 -->
-1/2

So the answer is -1/2.

Hope it helps!

Answer 5

-5/10

Answer 6

If a/b = 5/10 =0.5
then from above a = 0.5 b ...............(1)
To find the value of a-b/ b substitute expression in (1) in this term
Then ( 0.5b - 1b ) /b is - ( 0.5b )/ b or - 0.5 or -1/2

Answer 7

if a/b=5/10 and a-b/b?
solution

from a-b/b=0
then a=b/b=1
subtuting into eq. 1
a/b = 5/10
1/b = 5/10
.
. . b= 2

Answer 8

42

Answer 9

a/b = 5/10
a = 5b/10
a = 0.5b
[a -b]/b = [0.5b - b]/b
= -0.5b/b
= -0.5
[a - b ]/b = -0.5
