ANSWERS

Part 1: Multiple Choice

Part 2. Essay

Question 8. Calculate the value of the expression

a) (300 + 70) + 400 = 370 + 400 = 770

b) 998 – (302 + 685) = 998 – 987 = 1

c) 100 : 2 : 5 = 50 : 5 = 10

Question 9. Set up and calculate

a) 108 : 6 = 18

b) 620 : 4 = 155

c) 194 × 4 = 776

Question 10.

The company has the number of taxis as:

96 × 2 = 192 (cars)

The company has a total number of passenger buses and taxis as:

96 + 192 = 288 (cars)

Answer: 288 cars.

Question 11. The perimeter of quadrilateral MNPQ is:

30 + 25 + 25 + 50 = 130 mm

Question 12.

a) 1 m < 102 cm

Since 1 m = 100 cm and 100 cm < 102 cm, then 1 m < 102 cm.

b) 300 ml + 700 ml = 1 l

Since 300 ml + 700 ml = 1,000 ml and 1,000 ml = 1 l, then 300 ml + 700 ml = 1 l

Question 13.

a) 576 + 678 + 780 – 475 - 577 - 679

= (576 – 475) + (678 – 577) + (780 – 679)

= 101 + 101 + 101

= 101 × 3

= 303

b) (126 + 32) × (18 - 16 - 2)

= 158 × 0

= 0

ANSWERS

Part 1. Multiple Choice

Part 2. Essay

Question 9. Mental calculation

a) 460 mm + 120 mm = 580 mm

b) 240 g : 6 = 40 g

c) 120 ml × 3 = 360 ml

d) 1cm 3mm + 23mm = 13mm + 23mm = 36mm

Question 10. (students set up correctly themselves)

b) 76 : 4 = 19

c) 241 × 3 = 723

d) 963 : 3 = 321

Question 11. Calculate the value of the expression

Question 12. Solution

2 bags of rice weigh:

30 × 2 = 60 kg

2 bags of rice and 1 bag of corn weigh:

60 + 40 = 100 kg

Answer: 100 kg

Question 13.

a) Jug A contains the most water.

b) Jug B contains the least water.

c) Two different jugs to make 550 ml of water are: A and D

Because the total water in two jugs is: 300 ml + 250 ml = 550 ml

d) Arrange the jugs in order from least to most water: B, C, D, A

Question 14.

We have: A, O, C are 3 points on a straight line and O is the center of the circle

Thus, AC is the diameter of the circle with center O

So the radius of the circle is:

10 : 2 = 5 (cm)

Answer: 5 cm
