15 friends want to order pizza for dinner. They predict that each person will eat 1/3 of a pizza. How many pizzas should they order? Do divide 3/15
I meant 15/3.
I figured it out anyway.
Thanks
No.
3/15 = 1/5
That doesn't make sense, does it.
Please try again.
is is 15/3 thetefore5 pizzas?
To find out how many pizzas to order, you need to divide the total number of people (15 friends) by the fraction of a pizza each person will eat (1/3).
To divide a fraction, you multiply by its reciprocal. The reciprocal of 1/3 is 3/1, which is just 3.
So, to find the answer, we divide 15 by 1/3:
15 ÷ (1/3) = 15 × (3/1)
= (15 × 3) ÷ 1
= 45 ÷ 1
= 45
They should order 45 pizzas for dinner with 15 friends.
