Perform the following division. round the answer to three decimal places. use paper and pencil to calculate the problem. 0.64 ÷ 3.8 = 1.684 0.169 0.164 0.168

0.168

Step-by-step explanation:

0.64 ÷ 3.8

To divide this number first we need to remove the decimal point from the given problem 3.8

In 0.64 ,We have 64 after the decimal point so we multiply by 100

We multiply both numbers by 10

0.64* 100 is 64

3.8 * 100 is 380

Now we do 64 ÷ 38 0

We put 64 inside and 380 outside. We use long division

When we put decimal point at the top then we add 0 with 64

                              0 . 1 6 8 4

           380              640

                                 380

                     (subtract)

                                 260 0

                                 2280

                 (subtract)

                                   320 0

                                    3040

                          (subtract)

                                     160 0

                                      1520

                        (subtract)

                                       80  and it goes on

      quotient is 0.1684

When we round to three decimal places it becomes 0.168      

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
