Q: What is the value of the digit 5 in 5609?

(4) 5000. The digit 5 is in the thousands place, so its value is 5000.

Q: Which of the following is six thousand and fifty in numerals?

(3) 6050. Six thousand is 6000, and fifty is 50. Combining them gives 6050.

Q: What is the missing number in the box? 12/15 = ?/5

(4) 4.. To find the equivalent fraction, simplify 12/15 by dividing both the numerator and denominator by 3: 12 ÷ 3 = 4 and 15 ÷ 3 = 5. So, 12/15 = 4/5. The missing number is 4.

Q: Which of the following is the same as 6 km 20 m?

(3) 6020 m. 1 km = 1000 m. So, 6 km = 6000 m. Therefore, 6 km 20 m = 6000 m + 20 m = 6020 m.

Q: In the figure, which line is perpendicular to AB?

(4) IJ. Perpendicular lines form a 90-degree angle. Line AB is a horizontal line segment. Line IJ is a vertical line segment drawn on the grid. Vertical lines are perpendicular to horizontal lines, forming a right angle.

Q: Arrange the fractions in order from the smallest to the greatest. Fractions: 7/9, 1/2, 4/9

(2) 4/9, 1/2, 7/9. To arrange fractions, convert them to decimals or find a common denominator. Decimal values: 1/2 = 0.5 4/9 ≈ 0.444 7/9 ≈ 0.777 Ordering from smallest to greatest: 0.444, 0.5, 0.777. So, the fractions in order are 4/9, 1/2, 7/9. This corresponds to option (2).

Q: Jason has 300 stickers. Mabel has 50 fewer stickers than Jason. How many stickers do they have altogether?

(3) 550. Mabel has 300 - 50 = 250 stickers. Together, they have 300 (Jason) + 250 (Mabel) = 550 stickers.

Q: Jordan had 100 cards. He gave some cards to 10 friends. Each friend received 6 cards. How many cards did he have left in the end?

(3) 40. Total cards given away = 10 friends × 6 cards/friend = 60 cards. Cards left = 100 (total) - 60 (given away) = 40 cards.

Q: Candice was given $100 to buy a book and a recorder. How much change would Candice receive?

(1) $44.90. Cost of book = $17.20 Cost of recorder = $37.90 Total cost = $17.20 + $37.90 = $55.10 Change received = $100 - $55.10 = $44.90.

Q: The figure below is drawn on 1-cm square grid. The perimeter of Figure A is ____ cm.

(3) 18 cm. Count each 1-cm segment forming the outer boundary of Figure A. Vertical segments: 3 (left side) + 1 (internal drop) + 1 (internal rise) + 3 (right side) = 8 cm. Horizontal segments: 5 (bottom side) + 2 (top left) + 1 (internal horizontal) + 2 (top right) = 10 cm. Total perimeter = 8 cm (vertical) + 10 cm (horizontal) = 18 cm.
