Harley and Natalie are each given 2 1/3 kg of clay Harley makes as many balls of clay as he can from his clay. Each ball weighs 1/6 kg. Natalie makes ten more clay balls than Harley (each weighing the same).

If Natalie used up all her clay, how much does each of her clay balls weigh?

Respuesta :

Solution:

Note that:

  1. One ball made by Harley = 1/6 kg
  2. Each student was given 2 1/3 kg of clay
  3. Natalie made 10 more balls (same weight) than Harley.

Solving for how much balls made by Harley.

  • 7/3 ÷ 1/6
  • => 7/3 x 6
  • => 7 x 2
  • => 14 balls.

Solving for how much balls made by Natalie.

  • 14 + 10
  • => 24 balls

Finding out the weight of each ball made by Natalie.

  • 7/3 ÷ x = 24
  • => 7/3 × 1/x = 24
  • => 7/3x = 24
  • => 7 = 72x
  • => x = 7/72 kg

Natalie's balls weigh about 7/72 kg.
