Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she

SOVA2 [1]

Answer:

Softballs = (48/b)

Step-by-step explanation:

Given that,

Total number of softballs = 48

She wants to divide them evenly among b softball bags.

We need to find an expression that represents how many softballs she should put into each bag.

As it is dividing among b softball, it means we divide 48 and b. So,

$s=\dfrac{48}{b}$

Hence, the required expression is (48/b).
