Solve the problem if you have enough information. Tell any information that is not needed or that is missing.

Question 1.
Chloe walks about 3.8 kilometers every day. Katie walks about half as much. How many kilometers does Chloe walk every 40 days?
152 kilometers Chloe walks every 40 days.

Explanation:
Number of kilometers every day Chloe walks about = 3.8.
Katie walks about half as much.
Number of kilometers every 40 day Chloe walks = 40 × Number of kilometers every day Chloe walks about
= 40 × 3.8
= 152.

Question 2.
Gabe brought 1.3 liters of water, 2.19 liters of juice, and 1.8 liters of lemonade to a picnic. 19 people came to the picnic. At the end of the picnic, Gabe had 1.47 liters of drinks leftover. How much did everyone drink at the picnic?
Number of liters of drink everyone drank at the picnic = 0.20.

Explanation:
Number of liters of water Gabe brought to a picnic = 1.3.
Number of liters of juice Gabe brought to a picnic = 2.19.
Number of liters of lemonade Gabe brought to a picnic = 1.8.
Total number of liters of drinks Gabe brought to a picnic = Number of liters of water Gabe brought to a picnic + Number of liters of juice Gabe brought to a picnic + Number of liters of lemonade Gabe brought to a picnic
= 1.3 + 2.19 + 1.8
= 3.49 + 1.8
= 5.29.
Number of  people came to the picnic = 19.
Number of  liters of drinks leftover Gabe had = 1.47.
Number of  liters of drinks used in the picnic = Total number of liters of drinks Gabe brought to a picnic  – Number of  liters of drinks leftover Gabe had
= 5.29 – 1.47
= 3.82.
Number of liters of drink everyone drank at the picnic = Number of  liters of drinks used in the picnic ÷ Number of  people came to the picnic
= 3.82 ÷ 19
= 0.20.

Question 3.
A male dolphin at a water park eats about 11.83 kg of food in a day. A female dolphin eats about 10.76 kg of food in a day. $$\frac{2}{3}$$ of the food they eat is fish. How much food will both dolphins eat in a week?
Number of kgs of food both dolphins eat in a week = 158.13.

Explanation:
Number of kgs of food in a day a male dolphin at a water park eats = 11.83.
Number of kgs of food in a day a female dolphin at a water park eats = 10.76.
$$\frac{2}{3}$$ of the food they eat is fish.
Total of kgs of food in a day they eat = Number of kgs of food in a day a male dolphin at a water park eats + Number of kgs of food in a day a female dolphin at a water park eats
= 11.83 + 10.76
= 22.59.
Conversion:
1 week = 7 days.
=> Number of kgs of food both dolphins eat in a week = Total of kgs of food in a day they eat × 7
= 22.59 × 7
= 158.13.
