Malcom is filling bags with rice . He starts with a 5 1/4 pound container of rice and fills each bag with 5/8 pounds of rice . H
timama [110]

Answer:

Malcolm would fill 8 bags of rice.

Step-by-step explanation:

The size of the container of rice = 5\frac{1}{4} pounds = \frac{21}{4} pounds.

Each bag of rice has a capacity of \frac{5}{8} pounds.

The number of bags of rice that Malcolm fills = \frac{total quantity of rice}{capacity of each bag}

                                          =  \frac{21}{4} ÷ \frac{5}{8}

                                          =  \frac{21}{4} x \frac{8}{5}

                                          = \frac{42}{5}

                                          = 8\frac{2}{5}

Therefore, Malcolm would be able to fill 8 bags of rice.
