Explanation:

Step1: Identify metric weight unit

In the metric system, grams are used to measure weight. Liters measure volume, pounds are an imperial - system weight unit, and meters measure length.

Step2: Convert kilograms to grams for second question

We know that 1 kilogram = 1000 grams. So, 5 kilograms = 5×1000 = 5000 grams. Rita has 40 grams. The total is 5000 + 40=5040 grams.

Step3: Convert kiloliters to liters for third question

We know that 1 kiloliter = 1000 liters. So, 4 kiloliters = 4×1000 = 4000 liters. Adrianna has 45 liters. Since 4000>45, Ja'Vonn collected more water.

Answer:

1. Grams
2. 5040
3. Ja'Vonn
