Directions: Complete the practice speed problems below.
Show your work using the magic triangle for each problem.
Put your answer in the box to the right of your work.
Your answers should include the number and the correct unit.
You must be exact! Round to the nearest two decimal places when appropriate (examples: 1.02 hrs | 2.01 km | 3.2 m/s).
You will see a red circle when you get an answer wrong. You have a chance to fix those errors before your final submission. If you submit your assignment with incorrect answers, you will not get a high score. Make sure you check those red circles at the top and fix your answers before you submit this assignment!
Also, your answers will automatically save after each problem. You cannot lose your work. 😆😏
Before you begin, you will need to remember how to round to the nearesth hundreth decimal place. That is two numbers to the right of the decimal. Some of these answers require a rounded decimal number if it has more than two numbers to the right of the decimal. Being exact is very important in scientific measurement.

Question 3

Remember, we only need two decimal places. So the 7.237 has an extra number on the end. We don't need the thousandths place number.
We also round up when our last number is 5 or above. That thousandths number in this example is 7. Our answer should then be 7.24 because it is a number greater than 5 and rounds up.
Based on what you learned in this passage above, round 7.237 to the nearthest hundreth.
