Answer:1.To convert 180 grams to kilograms, we need to divide by 1000:

180 g ÷ 1000 = 0.18 kg

Therefore, Lynette used 0.18 kg of flour.

To find out how much flour is left in the bag, we can subtract the amount used from the original amount:

2 kg - 0.18 kg = 1.82 kg

So, there are 1.82 kilograms of flour left in the bag.

2.To compare their heights, we need to have both measurements in the same unit. Let's convert Jake's height to centimeters:

1.6 m x 100 cm/m = 160 cm

Jake is 160 centimeters tall.

To find out how much taller Jake is than his sister, we can subtract his sister's height from his:

160 cm - 95 cm = 65 cm

To convert this to meters, we divide by 100:

65 cm ÷ 100 = 0.65 m

Therefore, Jake is 0.65 meters taller than his sister.

3.The mass of the packages is given in grams, so we need to convert to kilograms:

240 g ÷ 1000 = 0.24 kg

Each package has a mass of 0.24 kg.

To find the total mass of all 5 packages, we can multiply the mass of one package by the number of packages:

5 packages x 0.24 kg/package = 1.2 kg

Therefore, the total mass of the packages is 1.2 kilograms.

4.Jonah drinks 200 milliliters of water 8 times a day, so we can multiply these two values to find how much water he drinks in total:

200 ml x 8 = 1600 ml

However, we want to express this in liters, so we need to divide by 1000:

1600 ml ÷ 1000 = 1.6 L

Therefore, Jonah drinks 1.6 liters of water in a day.
