nadezda [96]

Answer:

Wilhelmina will put 1.66 ounces of peanut butter on each sandwich.

Step-by-step explanation:

Given:

Ounces of peanut butter Wilhelmina has = 8.3

Number of sandwiches prepared by her = 5

According to the question:

She puts equal amount of peanut butter on each sandwiches.

So,

We have to find the quantity of peanut butter used for each sandwiches.

Here the distribution is equal so we have to use division method.

Let ounces of peanut butter applied on each sandwich be 'x'

⇒ x= \frac{Ounces\ of\  peanut\ butter}{No.\ of\ sandwiches}

⇒ x=\frac{8.3}{5}

⇒ x =1.66 Ounces

So each sandwich will get 1.66 ounces of peanut butter.
