The food factory served 60 customers yesterday. 2/3 of the customers ordered breakfast. 1/2 of the remaining customers ordered take-out. The rest of the customers ordered lunch. How many ordered lunch?
+60 First to solve this problem we need to make the denominator (or the base) of the fraction 60 because it is the total.
Let's start with 2/3!
First, we slip up 60 into 3 parts (Also known as dividing 60 by 3)
Which gets us 20
So 1/3 is 20 then 2/3 is 40!
"1/2 of the remaining customers ordered take-out"
We have 20 remaining customers because 60 - 40 (as we got from the last part) is 20.
1/2 of 20 is pretty much dividing it by 2 or splitting it in half. So 20 in half is 10
That means 10 ordered take-out!
"The rest of the customers ordered lunch"
10 ordered take out and 40 ordered breakfast so adding that together gives us
50!
Knowing there were 60 in total we just have to subtract 50 from 60 which gives us
10 as the answer!
