Answer:
Fred's dog weighed 33.75 pounds at the appointment in March
Explanation:
First you need to convert 25% to a decimal by moving the percent sign twice to the left and you will get 0.25.
Then you multiply 45 by 0.25 to find 25% of 45.
45 x 0.25= 11.25
After multiplying, you just have to subtract the product (11.25) by 45.
45 - 11.25 = 33.75
This is the same was doing 45-25%
