Lesson 6: Divide whole numbers by decimals

# Dividing whole numbers by decimals examples

One approach to dividing whole numbers by decimals is to convert both numbers into the same base, such as tenths or hundredths. Another technique is to multiply the numerator and denominator to eliminate the decimal from the denominator.

• That makes so much sense. Thanks for helping me Sal!
• Are there more ways to divide decimal’s
• Yes, there are more ways to divide decimals.
• on the last lesson he said diving a decimal by a whole number is the same as multiplying, so wouldnt 8 divided by 4 be 32?
• how do you do it with 770
• How would you say 4,800 hundredths? I noticed Sal stumbled with the pronunciation, so i was wondering. Would you say it, four-thousand-eight-hundredths, or a different way? Let me know what you think.

• i mean i kinda get this but how do you divide hundreths by ones
• To be honest, when they use the tenths it just makes it really easier instead of doing the other stuff. Thanks Sal!
• how do you do it with 770
• lets do 770 divided by 0.5.
we can make this easier by 770 divided by 5. we would set this up like
770
---
5
and if we did the division correct we would end up with 154, which we have to add the decimal back in, we would start it to the right of the 4 in 154, and move it to the left once. so your answer would be 15.4. hope this helped :3

• wait, if we put everythig in terms of tenths, wouldnt it be 20 tenths?

• When we do 80 tenths/4 tenths, we are asking how many groups of 4 tenths fit in 80 tenths. The answer is 20, because they fit 20 groups of 4 tenths in 80 tenths (20 * 4 tenths = 80 tenths).
