Lesson 3: Divide decimals by whole numbers

Dividing a decimal by a whole number example

To divide a decimal by a whole number, you can convert the decimal into a certain number of hundredths. After dividing the whole number into those hundredths, you can then convert the result back into a decimal form.

• Okay, I see a lot of confusion... So, 1.86 in 1.86 ÷ 2 can be written as 186 hundredths (hundredths is the smallest place value). Now, just divide 186 and 2 and get 93. Since we wrote 1.86 as 186 hundredths, write 93 as 0.93. This is because we need to divide back into decimals, and 93 ÷ 100 = 93/100 = 0.93. It's simple. :) :)

• Can you explain in a different way
• 1.86 = 186 hundredths

Divide 186 by 2. Result is 93. Remember we are dividing hundredths. So your quotient is 0.93.
• What is there’s a remainder? I’m still struggling with this.
• I'll try to guide you to the answer with questions.

Ask yourself this, what is a remainder?

Then think about multiplying in groups and totals

8 is 2 groups of 4 or 4 + 4

When Khan got his answer but never mentioned a remainder, what does that mean for the answer?

Hope this helps
• italics It doesnt explain the math im doing its like this:

bold*3.64÷7= hundredths÷7

*bold*3.64÷7= hundredths

*bold
3.64÷7=
• First of all, to get bold words, you wrap them around *. . .* The dotts I added to indicate the words/phrases. Italic or slanted phrases/words need to be wrapped around like: . . .

Coming to the point, if you write 3.64 in hundredths, it would be 364 hundredths, and you do 364 ÷ 7 = 52
Since you wrote 364 in hundredths, so do you for 52 (0.52). So 3.64 ÷ 7 is 0.52.

hope i helped :) <3
• can you explain it more please
• Hey, first it's 1.86 divided by 2, but then he converts the 1 to 100 hundredths, and then he converts the .86 into 86 hundredths which equals 186 hundredths. Then you have to do 186 HUNDREDTHS divided by 2, and get 93 hundredths. Which equals 0.93

Hope This Helped!

• how would you divide 16.8 divided by 8?
• Since 168 is 160+8, 168 divided by 8 is 20+1, or 21.

Because 16.8 is 1/10 of 168, 16.8 divided by 8 is 1/10 of 21, which is 2.1. The answer is 2.1.

Have a blessed, wonderful day!
• i am soo confused pls help me TYSM^^
