For the final step in calculation, Ezra accidentally divided by 1000 instead of multiplying by 1000. What should he do to his incorrect answer to correct it?
A Multiply it by 1000
B Multiply it by 100000
C Multiply it by 1000000
D Square it
Solution
Correct Answer: Option C
ধরি, সংখ্যাটি 1000
∴ 1000 দিয়ে ভাগ করলে হতো = 1000/1000 = 1
∴ 1000 দিয়ে গুন করলে হতো = 1000 x 1000 = 1000000
∴ ঠিক করতে হলে = 1000000 দিয়ে গুন করতে হবে।
