Algebra (relevant for 6Q3 59.1-59.2)

To divide a decimal with four decimal places by 0.1, you can use a straightforward method that involves shifting the decimal point. When dividing by 0.1, you effectively multiply the number by 10. This is because dividing by a fraction (or decimal) is equivalent to multiplying by its reciprocal. The reciprocal of 0.1 is 10.

For example, consider the decimal 0.1234. To divide 0.1234 by 0.1, you multiply 0.1234 by 10. This shifts the decimal point one place to the right, resulting in 1.234. Therefore, $\frac{0.1234}{0.1}=1.234$. This method can be applied to any decimal with four decimal places when dividing by 0.1.
