Question

Find a number that is approximately $1.5$ times $61,040,000,100$.
Write the result as the product of a single digit and a power of $10$.

Answer 1

To find a number which is approximately $1.5$ times of $61,040,000,100$ .We should multiply and solve the product of $1.5$ and $61,040,000,100$.

A number which is approximately $1.5$ times of $61,040,000,100$ $=1.5\times 61,040,000,100$

$=91,560,000,150$

$91,560,000,150\approx$ $90,000,000,000$. ( Round off to nearest $10,000,000,000$)

$90,000,000,000=9\times 10,000,000,000$ (Factor out $9$)

$9\times 10,000,000,000=9\times {10}^{10}$ ( Write $10,000,000,000$as a power of $10$)

Result as the product of a single digit and a power of $10$ $=9\times {10}^{10}$
