In murphy’s battery manufacture company , 400 kg of lead, 90 kg of carbon, 50 litres of battery acid, and 60 kg of rubber are used per day to make batteries. A. What is the ratio of the raw materials used per day, reduced to lowest term?

Answer 1

To find the ratio of the raw materials used per day, we need to divide the quantities of each material used by their greatest common divisor (GCD).

The GCD of 400, 90, 50, and 60 is 10.

So, the ratio of the raw materials used per day, reduced to lowest term, is:

400 kg / 10 : 90 kg / 10 : 50 L / 10 : 60 kg / 10

which simplifies to:

40 kg : 9 kg : 5 L : 6 kg.
