Question

Six items purchased at a grocery store weigh 14 kilograms. One of the items is detergent weighing 720 grams. What is the total weight, in kilograms, of the other five items?

Answer 1

To solve this problem, convert all the measures to the same unit. In this case, convert all the measures given in grams to kilograms.

$720g\cdot\frac{1kg}{1000g}=0.72\operatorname{kg}$

To find the total weight of the other five items, substract the weight of the detergent to the total weight of the six items.

$14\operatorname{kg}-0.72kg=13.28\operatorname{kg}$

The total weight of the other five items is 13.28kg.
