And animals weight change from 12 pounds to 16 pounds what was the percent increase to the nearest whole number
amm1812
That's a 33% increase.

I calculated this using the formula:

\frac{|n-o|}{o} * 100

Where n = the new value (16 in your question), o = the old value (12 in your question) and the result is outputted as a percent increase.  You can check that this is correct by finding 33% of 12, adding the result to 12, and checking that the result equals your "new" number.  

Note that 33% is only an approximation as your question requires a number rounded to the nearest whole.

How to solve 2 3/4 - 1 5/8
daser333 [38]

Answer:

1 1/8

Step-by-step explanation:

First, Make the first fraction into a new one with an equal denominator. (3/4 x2= 6/8)

Then, subtract the whole numbers (2-1=1) and the fractions (6/8-5/8= 1/8)

Lastly, add your two differences together and you get 1 1/8.
