He folds a piece of paper into three parts and shades two parts. Then he folds the paper into four parts and shades 1/4 of the shaded part. Ricardo decides he needs 1/4 cup of olive oil. Is he right? Explain

Answer 1

He needs 1/6 cup since 2/3 times 1/4 equals 1/6. he isn't right

Answer 2

Ricardo is wrong.

Explanation:

Ricardo's recipe for 4 loaves of bread requires 2/3 cup of olive oil.

Now we are given that he wants to make 1 loaf.

So, 4 loaves requires cup of oil =
`(2)/(3)`

So, 1 loaf requires cup of oil =
`((2)/(3))/(4)`

=
`(2)/(12)`

=
`(1)/(6)`

Thus he requires 1/6 cup of oil to make 1 loaf .

While he decided he needs 1/4 cups .

So, Ricardo is wrong
