7.19 divided by 58 estimate the quotients
lozanna [386]

Answer:

0.124

Step-by-step explanation:

\frac{7.19}{58}

To divide the numbers, we need to remove the decimal point

To remove decimal point , we multiply top and bottom by 100

\frac{719}{5800}

Use long division. After using decimal point at the top we can include any number of zeros with 719

                            . 1 2 3 9

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

        5800         7190

                          5800

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

                          13900

                          11600

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

                           2300 0

                           1740 0

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

                            56000

                            52200

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

                             3800 0

Division goes on ............

Estimate the quotient to 3 decimal places

Quotient = 0.124
