At a shelter, 15% of dogs are puppies. There are 60 dogs at the shelter.How many are puppies?
Ostrovityanka [42]
It is important to look at all the information’s already given in the question. Those information’s will come in handy while solving the question.
Number of dogs in the shelter = 60
Percentage of puppies in the shelter = 15%
Then
Number of puppies in the shelter = (15/100) * 60
                                                     = 900/100
                                                     = 9
So there are a total of 9 puppies in the shelter. I hope the procedure is clear enough for you to understand. I am glad to have helped you.

Two less than 2 times a number is the same as the number plus 64. What is the number?
Alex Ar [27]
Set it up as an equation. "A number" is x.

2x-2=x+64

Move all of the x terms to one side by subtracting x from both sides, then add 2 to both sides to isolate x.

X=66

The number is 66
