Question

William helped new students move desks into the classroom. If 26 desks have a mass of 243 kg, what is the mass of one desk? Round off your answer to the nearest hundredth.

Answer 1

Answer: 9.35 kg

Step-by-step explanation:To find the mass of one desk, we can divide the total mass of the desks by the number of desks.

Given that there are 26 desks with a total mass of 243 kg, we can set up a proportion:

26 desks / 243 kg = 1 desk / x kg

To solve for x, we can cross multiply:

26 * x = 1 * 243

This simplifies to:

26x = 243

Now, we can solve for x by dividing both sides of the equation by 26:

x = 243 / 26

Using a calculator, this gives us approximately 9.35 kg.

Therefore, the mass of one desk is approximately 9.35 kg.
