Question

Only 60% of the pizzas ordered for the party were eaten. 9 pizzas were eaten. How many pizzas were ordered?

Answer 1

Answer: hope this helps ♡

15 pizzas were ordered.

Explanation:

60% = 9 pizzas (eaten)

40% = ? pizzas (not eaten)

60% = 0.6

0.6x = 9 (we know that 9 or 0.6x pizzas were eaten)

solve for x:

0.6x = 9

(0.6x) ÷ 0.6 = 9 ÷ 0.6

x = 15 (sorry if there is any confusion)

Answer 2

15

Explanation:

Let the Total no. of pizzas be = X

60% of the pizzas were eaten = 9 Pizzas (given)

i.e 60% of X = 9

60/100 × X = 9

X = 9 × 100 \ 60

X= 15

Hence, the total no. of pizzas ordered are 15.
