Grade 5 STAAR Math Question: How Many Watts Does Each Monitor Use?

Question

The 3 monitors in a classroom use a total of 0.87 watt of electricity. Each monitor uses the same number of watts. How many watts does each monitor use?

Answer 1

Be sure to read the question carefully. What is the question asking us to find? What information is given?

The 3 monitors in a classroom use a total of 0.87 watt of electricity. Each monitor uses the same number of watts. How many watts does each monitor use?

We need to find out how many watts of electricity each monitor uses.

We know that there are three monitors in the classroom. Together, they use a total of 0.87 watts of electricity. Each monitor uses the same number of watts.

Since we already know the total number of watts used, we will need to divide that number up by the number of monitors to find out how much each monitor uses.

Now we can set up our equation:

0.87 divided by 3 = ___

We can use scratch paper to solve:

Be sure to label your answer:

Ans. 0.29 watts each

Answer 2

This is an easy problem. All you need to do to find the answer is divide the number of watts used by the number of monitors sucking the power. So, 0.87 (total number of watts) divided by 3 (how many monitors are there?). And just like that, you know that each monitor uses 0.29 watts of power. Have a nice day!! 😀

Answer 3

3/1 = 0.87/x

solve for x

Answer 4

Answer 5

To find out how many watts each monitor uses, we need to divide the total watts by the number of monitors.

Total watts = 0.87 watts

Number of monitors = 3

So, we divide 0.87 by 3
