7. Nina has 2/3 cup of shampoo left in the shampoo bottle. She uses 1/8 cup of shampoo to wash her hair. If nina washes her hair every day, how many days can she wait before opening a new bottle of shampoo?

Respuesta :

Answer:

5 days

Step-by-step explanation:

Make 1/8 and 2/3 have the same denominator

the Least common multiple is 24

1/8 becomes 3/24 and 2/3 becomes 16/24

she can use it 5 more times with a remainder of 1/24 of a cup of shampoo remaining
