Respuesta :

Answer:

3/4 cup of coconut oil

Step-by-step explanation: 2/3 cup of toothpaste equals 1/2 a cup of coconut oil. If you split 2/3 in half you get 1/3. And if you split 1/2 in half you get 1/4. Since there are 3 thirds in a cup you will have 3/4 cups of coconut oil because for every 1/3 cup there is 1/4 cup of coconut oil.

1/3+ 1/3+ 1/3= 3/3 or 1

1/4+ 1/4+ 1/4= 3/4

The amount of coconut required per cup of toothpaste is 0.75 cups.

Amount of coconut oil = 1/2 cup

Amount of tooth paste = 2/3 cup

This can be related thus :

  • 1/2 coconut oil = 2/3 cups of toothpaste

Hence, to make 1 cup of tooth paste, let amount of coconut oil required = x

1/2 = 2/3

x = 1

Cross multiply

2/3x = 1/2

0.66666x = 0.5

x = 0.5 / 0.666666

x = 0.75

Therefore, 0.75 cup of coconut oil is required per cup of toothpaste.
