    Answer:

    Number on ants on Earth = 1.2 × 10¹⁵

    Step-by-step explanation:

    1 quintillion = 10¹⁸ or (1000000000000000000)

    ∴ 12 quintillion = 12 × 10¹⁸

    12 quintillion = 10,000 × Number of ants on Earth

    Let the number of ants on Earth = n

    12 quintillion = 10,000 × n

    dividing both sides by 10,000

    12 quintillion ÷ 10,000 = n

    n = \frac{12\ \times\ 10^{18} }{10,000} \\n =  \frac{12\ \times\ 10^{18} }{10^{4}}\\n = 12\ \times\ \frac{10^{18}}{10^{4}} \\applying\ the\ second\ law\ of\ indices\ (\frac{x^m}{x^n} = x ^{m-n})\\ n = 12\ \times\ 10^{(18 - 4)\\n = 12\ \times 10^{14}\\in\ standard\ form\\n = 1.2\ \times 10\ \times\ 10^{14}\\\therefore n = 1.2\ \times\ 10^{15}

    Number on ants on Earth = 1.2 × 10¹⁵
