Well, there are a few ways but you do it like you would integers. For instance, -6 + 2 = -4.  -\frac{3}{5} + \frac{1}{5} = -\frac{2}{5} Also if you have fraction with different denominators you would first make the fractions with the same denominator and then add and subtract like you would integers like
-4 - 6 = -10

What single percentage change is equivalent to a 7% decrease followed by a 22% decrease?
quester [9]

Answer:

<em>The single percentage change is 27.46%</em>

Step-by-step explanation:

<u>Percentage</u>

Suppose x is the initial number. It will be decreased by 7%.

(7/100)x=0.07x

x - 0.07x = 0.93x

This last number will be decreased by 22%.

0.93x*(22/100)=0.2046x

0.93x-0.2046x=0.7254x

The last number is 72.54% of the initial number. This is equivalent to a single decrease of:

100% - 72.54% = 27.46%

The single percentage change is 27.46%

Blizzard [7]
So how many does he have left

25-16=9
9 floors left

the want a percentage so 9 out of 25
percent is out of 100
a hack for this specific problem is that 25 is exactly 1/4 of 100 so
9/25 times 1=the same thing so
9/25 times 4/4 (simplifies to 1)=(9 times 4)/(25 times 4)
36/100
this is out of 100 so
36%

of course there is a legit way of solving this problem but this is a hack (this works for factors of 100 like 2,4,5,10,20,25,50)
