Anastasia is grocery shopping with her father and wonders how much shopping is left to fo. "We already have 60% of the items on our list," her father says. Anastasia sees 12 items in the cart. How many grocery items are on the list?"
The answer is 20. The way I do it is divide 12 by 6 then multiply it by 10 (it works as long as the denominator is ten).
Answer: 20
Step-by-step explanation:
Given : The number of grocery items of list they already have= 12
The percentage of grocery items they have now = 60%
Which can also be written as 0.60
Let x be the total grocery items in the list , then we have the following equation :-
\(0.60x=12\)
Divide 0.60 both sides , we get
\(x=\dfrac{12}{0.6}=20\)
Hence, the number of grocery items are on the list =20
