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?

Answer:

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?

Answer:

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?

Answer:

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.

Question 4.

A science experiment calls for 13 mL of red food coloring, 2 mL of blue food coloring, and 1 mL of yellow food coloring. How many milliliters of food coloring are needed so that every student in the class can perform the experiment?

Answer:

19 milliliters of food coloring are needed so that every student in the class can perform the experiment.

Explanation:

Number of mL of red food coloring a science experiment calls for = 13.

Number of mL of blue food coloring a science experiment calls for = 2.

Number of mL of yellow food coloring a science experiment calls for = 1.

Total number of mL of all food coloring = Number of mL of red food coloring a science experiment calls for + Number of mL of blue food coloring a science experiment calls for + Number of mL of yellow food coloring a science experiment calls for

= 13 + 2 + 1

= 15 + 1

= 16.
