How to show your work for 9 divided by 2.43

Answers

Answer:

3.70

Step-by-step explanation:

9 divided by 2.43

To divide decimal numbers we need to remove the decimal point

(9)/(2.43) =(9 \ times \ 100)/(2.43 \ times \ 100) =(900)/(243)

Now use long division to divide the numbers

                                    3.70370

                               --------------------------------    

                  243          900

                                   729

                              ---------------------------(subtract)

                                   1710                      (add decimal point at top)

                                   1701

                              ---------------------------

                                       900                (add 0 at top)

                                        729  

                                ---------------------------(subtract)

                                          1710                      (add decimal point at top)

                                          1701

                                    ---------------------------

                                              9

So answer is 3.70
Just do normal division, just like ignore the decimal point. for a moment once you got your answer bring back the decimal point back up to your answer. You would get 0.27 as your answer.

You have 3/5 cup of oatmeal in your cupboard. A recipe for cookies calls for 1/4 cup of oatmeal . How much oatmeal would you have left if you made the cookies ??

Answers

Answer:

The recipe calls for 4/3 cups of oatmeal and 9/2 cups of flour.

If we convert them to a common denominator, we have 8/6 cups of oatmeal and 27/6 cups of flour, so, the ratio is 8:27.

If you use 6 cups of oatmeal and 9 cups of flour, the ratio will become 2:3 and will no longer be proportional
