Rename 4 thousands 7 hundred = 47
The correct renaming of “4 thousands 7 hundred” is 4700. Explanation: “4 thousands” means 4 × 1000 = 4000, and “7 hundred” means 7 × 100 = 700. Adding these together gives 4000 + 700 = 4700. The number 47 is much smaller and does not correspond to the sum of these values. Steps: Convert […]
Michael, the art elective programme student, is working on another assignment. He designs a rectangular pattern measuring 45 mm by 42 mm. He is required to use identical rectangular patterns to form a square. The maximum area of the square allowed is 1.6m^2. (i) How many patterns does he need to form the smallest square? (ii) What are the dimensions of the largest square that he can form?
Answer: (i) 36 patterns (ii) 126 mm by 126 mm Explanation: This problem involves concepts from geometry and optimization, specifically focusing on maximizing the area of a square within a rectangular grid pattern. The key idea is to determine how many smaller patterns (rectangles) can be arranged to form the smallest possible square, and what […]

Let’s solve each problem step-by-step. Q1: Kavitha’s Laptop Cost Answer: The laptop costs $2,100. Explanation: Kavitha saved 1/3 of the laptop’s cost in the first month, then $125 less in the second month, and the remaining $525 in the third month. Let the total cost be \( x \). Steps: First month: \(\frac{1}{3}x\) Second month: […]
Which division expression is shown in the model?
Answer: The division expression shown in the model is $3 \div \frac{1}{2}$. Explanation: The model displays 8 shaded squares, each representing $\frac{1}{4}$ of a whole, totaling $2$ (since $8 \times \frac{1}{4} = 2$). The question asks which division expression is shown, and among the options, the one that matches the visual is $3 \div \frac{1}{2}$ […]
