5. Solve Exercise 5 Page 32 Math Textbook Grade 3

Problem: A farm raises cows and chickens, with 1,020 cows on the farm. The number of chickens on the farm is 8 times the number of cows. How many cows and chickens does the farm raise in total?

Solution Guide:

Step 1: Calculate the number of chickens the farm raises = number of cows x 8.
Step 2: Calculate the total number of cows and chickens the farm raises = number of cows + number of chickens.

Answer:
The farm raises the number of chickens:
                     1,020 x 8 = 8,160 (chickens)
The total number of cows and chickens the farm raises is:
                   1,020 + 8,160 = 9,180 (chickens)
                                     Answer: 9,180 chickens.

6. Solve Exercise 6 Page 32 Math Textbook Grade 3

Problem: An has 1 liter of milk. An pours 500 ml of milk for grandparents and evenly pours the remaining part into 2 glasses. How many milliliters of milk does each glass contain?

To solve:
Convert: 1 liter = 1,000 milliliters
Step 1: Calculate remaining milk = Amount of milk An has - 500 ml.
Step 2: Milliliters of milk in each cup = Remaining milk : 2.

Answer:
Convert: 1 liter = 1,000 milliliters
An has the remaining milliliters of milk:
1,000 : 2 = 500 (ml)

Each cup contains milliliters of milk:
500 : 2 = 250 (ml)
Answer: 250 ml.

Solution guide:
Weight of dog = weight of chicken x 2.
Weight of cat = weight of chicken ÷ 2.

Answer:
The weight of the dog in kilograms is:
                         2 500 x 2 = 5 000 (g)
The weight of the cat in kilograms is:
                        2 500 ÷ 2 = 1 250 (g)
Convert 5 000 g = 5 kg
1 250 g = 1 kg 250 g.
