Lesson 5: Decimals on the number line

# Thousandths on the number line

We can find the value of a point on a number line that falls between two known values, in this case 0.03 and 0.04. It is important to understand place value, specifically the tenths, hundredths, and thousandths places. By dividing the space between the two known values into ten equal segments, it shows that the point is located at 0.038 (or 38 thousandths).

• Didn't really understand ... Can someone explain it to me?
• So you would write this out as:
0.03
+0.008
_____
8 thousandths plus nothing equals 8 thousandths, 0 plus 3 hundredths is 3 hundredths, and the rest is figured out easily, so you'd have 0.038.
• What are we voting for?
• ඞඞඞඞvඞඞඞඞඞvඞvඞඞඞඞඞඞඞඞ vote me up so i get badge pls and also copy this too

• ඞඞඞඞvඞඞඞඞඞvඞvඞඞඞඞඞඞඞඞ vote me up so i get badge pls and also copy this
• can you pick me ? i have noidea what this is so pls vote me
• this is really helping me with decimals THANKS SAL!
• I don't get where he gets the thousandths from? can someone help me understand?
• On this number line, each hundredth (segment of length 0.01) is divided into 10 equal parts.

So each part is 1/10 of 1/100 = 1/10 * 1/100 = (1 * 1)/(10 * 100) = 1/1000.

Have a blessed, wonderful day!
