Vikentia [17]

Answer:

Cora put 3600 apple slices in each bowl.

Step-by-step explanation:

Cora sliced 18 kg of green apples for a Party.

She divided the Apple slices equally between 5 large bowls.

We need to find how many grams of Apple slices did Cora put in each bowl.

Since,

1 kg = 1000 grams

18 kg = 18000 grams

To find how many grams of Apple slices did Cora put in each bowl, divide total apples by total no of bowls.

$x=\dfrac{18000}{5}\\\\=3600$

Hence, Cora put 3600 apple slices in each bowl.
