(h)

_____? 582 times

Answer

58200

(j)
Answer

1000 hundreds are required to make one lakh.

(k)
Answer

Yes, the statement is true. Handy Hundreds can show numbers like 300, 500, 700 which are multiples of 100. Thoughtful Thousands can only show multiples of 1000 (like 1000, 2000, 3000), so it cannot show 300, 500, or 700. Tedious Tens can show these numbers but would need many more button presses.

Explanation

(a) 400 ÷ 100 = 4 presses (b) 3700 ÷ 100 = 37 presses (c) 10000 ÷ 100 = 100 presses (d) 53000 ÷ 100 = 530 presses (e) 90000 ÷ 100 = 900 presses (f) 97600 ÷ 100 = 976 presses (g) 100000 ÷ 100 = 1000 presses (h) 582×100582 \times 100 = 58200 (i) 100×100100 \times 100 = 10000 (j) 1000×1001000 \times 100 = 100000 (k) The chapter explores the concept that different calculators with different buttons can show different sets of numbers. Numbers that are multiples of 100 but not multiples of 1000 (like 300, 500, 700) can be shown by Handy Hundreds but not by Thoughtful Thousands.
