1/10 of Mr. Jones paycheck goes to helping rescue puppies. Let’s make this explanation easy and say Mr. Jones makes $1,000 a paycheck. 1/5 of this paycheck would be $200 (1,000/5 = 200). Of this $200, half of it goes to rescuing puppies (200/2 = 100). $100 of Mr. Jones donation goes to rescuing puppies. 100 is 1/10 of his paycheck (100 • 10 = 1000).
