Prime factorization of 620:
620
2 310
2 155
5 31
31 1
Step-by-step explanation:
3.7x - 0.20x = 17.5
3.5x = 17.5
x = 17.5/3.5
x = 5
First, convert 3 into a fraction with denominator 8.
(3 pizzas)(8/8 pizzas)=24/8 pizzas
Then, divide 24/8 pizzas by 2/8 pizzas per 1 person.
(24/8 pizzas)(2/8 pizzas/person)
Dividing by a fraction is the same as multiplying by the reciprocal:
(24/8)/(2/8)=(24/8)×(8/2) the 8s cancel and you are left with 24/2=12
3 pizzas will feed 12 people.
