Answer:
50%
Step-by-step explanation:
Well you do 30/20 = 1.5
1.5 - 1 = .5
.5 = 50%
Here are two slightly different ways to look at it.
Both ways do exactly the same thing.
<u>Way #1:</u>
Divide (the new number) by (the old number)
349 / 320 = 1.090625
Change the quotient 1.090625 to percent.
To change any number into percent, multiply it by 100, or move the decimal point 2 places to the right.
1.090625 ==> 109.06 %
The new number (349) is 109.06% of the old number (320).
But the old number was 100% of itself. So the new number
is <em>9.06% more</em> than the old number was.
================================
<u>Way #2:</u>
How much bigger is the new number ?
(349 - 320) = 29 bigger
Divide the increase by the old number:
29 / 320 = 0.090625
Change the quotient to a percent.
0.090625 = 9.06%
The <em>increase</em> is<em> 9.06%</em> of the old number.
ALL yourr doing is just adding 8 and 36
y= 4\frac{1}{2} or y= 4.5
