Answer:
The ratio of total puppies to brown puppies is 3 for 1. For every 3 puppies there is 1 brown puppie.
Step-by-step explanation:
In order to find the ratio between the total puppies to brown puppies we need to take the total amount of puppies , that is, the sum of all the puppies and divide it by the number of brown puppies. So we have:
ratio = total amount of puppies/brown puppies
ratio = (3+2+1)/(2) = 6/2 = 3/1
The ratio is for every three puppies we have one brown puppie.
112% of original=28
percent measn parts out of 100
112%=112/100=1.12
'of' means multiply
112% of original=28 means
1.12 times original=28
divide both sides by 1.12
original=25
original bill was $25
