Question

Engage:
The conference room receives the aftemoon sun. The room temperature was found to be 35 s^ The janitor turned on the air-few minutes the thermometer recorded it conditioning unit. After a 223 degrees * C What was the estimated change in temperature? Estimating is an educated guess: There are times when an estimate is needed and not the actual one
Let us solve and analyze the solution to the problem. aligned 36.50\\ underline .2230 aligned 37°C -22°C 15°C estimated change So 18 degrees * C is the estimated change in temperature.

1 How is estimation done in the solution that we have in the problem?

2 What was done first to the
numbers?

3 What was done next? to be

4 Let us compare the actual answer to the estimated one Are the difference the same or different? How near or far is the estimated answer to the actual one?

5. What will you do if the estimated answer is too large or small Gompared to the actual one?​

Answer 1

Given :    Estimating is an educated guess: There are times when an estimate is needed and not the actual one

36.5°C   - 22.3°C

37°C - 22°C = 15°C

To Find : 1 How is estimation done in the solution that we have in the problem?

What was done first to the numbers?

What was done next

compare the actual answer to the estimated one

Solution:

Estimation done in the solution is by rounding off the figure and    then doing mathematical operations.

First number were rounded off

36.5°C = 37°C

22.3°C  = 22°C

Then Subtraction was performed

37°C - 22°C = 15°C

Actual = 36.5°C   - 22.3°C = 14.2°C

Difference =  15°C  -  14.2°C = 0.8°C

 0.8°C far is the estimated answer to the actual one

We can rounding off  taking greatest integer  

36°C - 22°C  =  14°C  more closer to actual
