**Benchmark 6.2.7Locate rational numbers on a number line.**~ locate decimal numbers on a number line**Machinists and other skilled workers use decimal rulers to**make measurements! Some use Vernier Calipers**Some use hundredth scales.**This makes their measurements very accurate.**You can also put decimals on a number line to compare and**order them. DecimalsAs you read a typical number linefrom left to right, the decimals will become greater, and get closer to the next whole number.**We can use place value to locate our decimals on the number**line.**To do that, we must look at the intervals on the number**line.**What if two numbers have different place values?**Example: 0.7 and 0.53**The easiest way to fix that is to add zeros to make your**decimal numbers have the same place value. Remember! Adding on zeros will NOT change the value of your decimal number!**Add a 0 to 0.7 = 0.70.70 is larger than .53, so it will come**after 0.53 on the number line. 0.53 0.70**Now, let’s try to locate some decimal numbers on a number**line!**What number does point N represent on the number line below?**Remember to look at the intervals! Correct! 2.6**What number does point S represent on the number line below?**Correct! 4.8**What numbers are represented by the letters A, B, and C?**A B C A = 4.81 B = 4.93 C = 5.04**Now, let’s do some independent practice!**Turn to page 2 in your handout!
