For this case we can make the following rule of three:
2250 -----------> 100%
600 -------------> x
From here, we clear the value of x.
We have then:
[tex]x = (600/2250) * (100)
x = 26.66666667%[/tex]
Therefore, the decrease in percentage weight is:
[tex]100 - 26.66666667 = 73.33333333%
[/tex]
Round to the nearest whole number:
x = 73%
Answer:
the percent decrease in the puppy's weight rounded to the nearest whole number is:
