8+11=19. For an example: If I already have 8 pigs at the animal farm, and one of my friends brings 11 more pigs, I will have a total of 19 pigs because 9 pigs plus 11 more pigs equals 19 pigs altogether at the animal farm.
Step 1) Set up a proportion
Proportion: percent / 100 = x / number
In context of the problem, the proportion is: 40 / 100 = 10 / number
Step 2) Cross-multiply and solve
100 x 10 = 40 x N
1000 = 40N
N = 25
Answer: The number is 25
