Question

A customer orders 8 bags of rice that each weigh 1/2 kg and 12 packets of popcorn that each weigh 150g what is the total mass of the order? Show your thinking

Answer 1

convert 1/2kg to grams:


`(1)/(2) kg = 0.5kg = 500g`

add the weights times their quantity:


`total \: mass= (8 * 500) + (12 * 150)`


`total \: mass = 4000 + 1800 = 5800g`

the solution is a total mass of 5800g or 5.8kg
