Question

Rachael decided to have bouncy balls as a party favor. She determines that her ratio of bouncy balls to guests is 9:3. Explain how to find the number of balls needed for 30 guests.

Answer 1

Answer:

90

Step-by-step explanation:

Ratio Bouncy ball to guests = 9:3

Means,

you need 9 Bouncy ball 3 guests.

Unitary method,

if 3 guests requires = 9 Bouncy balls

then

  1 guest requires = 9/3 = 3 Bouncy balls

9x:3x

3x=30 given the number of guest

x=10

9x= 9 x 10 = 90  Bouncy Balls
