mikayla made 6.88 pounds of trail mix.she divided the mix into servings that each had 0.8 pounds.how many servings did she make?

Question

I need to use long division

 

Answer 1

When dividing with decimals, you want the divisor (0.8) to be a whole number and the dividend (6.88) doesn't have to be a whole number.

 

To change the divisor to a whole number, multiple 0.8 by 10 = 8

If you multiple the divisor by any number, you must do thesame to the dividend, 6.88 x 10 = 68.8

 

So now you can divide 68.8 ÷ 8 = 68.8 ⁄ 8 = 8.6

 

     8.6

8|68.8

  -64

     48

    -48

       0

Answer 2

To make it easy for you, start by moving the decimal places. You can multiple both 6.88 and 0.8 by 100

 

6.88*100=68800..when you put the 2 decimal place it is 688.00=668

0.8 *100=800..when you put the 1 decimal place it is 80.0=80

 

Do you long division 688/80

688/80= 8 reminder 48....(688-640=48)

Decimal place begins...add zero to 48, making it 480

480/80=6

 

so you get 8.6

 

I hope you understood and that this helps....
