Jaylen is making pancakes. He has 1 liter of pancake mixture. If Jaylen is using
Finger [1]

He can make 4 pancakes with the whole mixture.

<u>Step-by-step explanation:</u>

It is given that,

  • Jaylen has a total of pancake mixture = 1 liter.
  • The amount of pancake mixture he uses to make 1 pancake = 1/4 liter.

You need to find the number of pancakes he can make using the 1 liter of pancake mixture.

<u>To find the number of pancakes :</u>

let us take 'N' be the number of pancakes he can make using 1 liter of mixture.

⇒ Total mixture = amount of mixture needed for 1 pancake × N

⇒ 1 liter = 1/4 liter × N

⇒ 1 = N/4

Cross multiply the denominator 4 to the other side, to find N

⇒ 1 × 4 = N

⇒ N = 4 pancakes

Therefore, he can make 4 pancakes with the whole mixture.
