Q: What is the value of 4 thousands + 2 hundreds + 6 ones?

(2) 4206. 4 thousands = 4000. 2 hundreds = 200. 6 ones = 6. Total value = 4000 + 200 + 6 = 4206.

Q: What is the missing number in the box? 6 2/5 = ?/5

(4) 32. To convert the mixed number 6 2/5 to an improper fraction, multiply the whole number (6) by the denominator (5) and add the numerator (2). (6 × 5) + 2 = 30 + 2 = 32. So, 6 2/5 = 32/5. The missing number is 32.

Q: There are 9345 men and 8704 women in a stadium. What is the total number of people in the stadium? Round this number to the nearest 100.

(1) 18 000. Total number of people = 9345 + 8704 = 18049. To round 18049 to the nearest 100, look at the tens digit, which is 4. Since 4 is less than 5, we round down. The hundreds digit remains 0, and the tens and ones digits become 00. So, 18049 rounded to the nearest 100 is 18000.

Q: Mindy had 4/5 kg of flour at first. After she had used some of the flour to make noodles, she had 1/3 kg of flour left. How much flour did she use to make noodles?

(2) 7/15 kg. Flour used = Flour at first - Flour left. Flour used = 4/5 - 1/3. To subtract fractions, find a common denominator, which is 15. 4/5 = (4 × 3) / (5 × 3) = 12/15. 1/3 = (1 × 5) / (3 × 5) = 5/15. Flour used = 12/15 - 5/15 = 7/15 kg.

Q: KLMN is a rectangle. Find ∠ t.

(3) 30°. In a rectangle, all interior angles are 90°. Therefore, ∠KNM = 90°. The angle ∠KNM is divided into two parts: 60° and ∠t. So, ∠t + 60° = 90°. ∠t = 90° - 60° = 30°.
