A concreter has a 36kg bag of cement mix on the back of his ute. the bag broke and 1/10 was lost. How much cement mix was left in the bag.?

32.4 kg were left in the bag

Step-by-step explanation:

1. Let's check the information provided for answering the question:

Weight of the bag of cement = 36 kg

Fraction of the cement bag lost = 1/10

2. How much cement mix was left in the bag?

For calculating how much cement was left, we use this equation:

x = Cement left in the bag

x = 36 - 1/10 * (36)

x = 36 - 36/10

10x = 360 - 36 (Multiplying by 10 at both sides)

10x = 324

x = 32.4 kg
