Explanation: Decimals represent fractions
with denominators of 10, 100, 1000, and so on.
Therefore, in order to write 3/5 as a decimal, we must first find a
fraction equivalent to 3/5 with a denominator of 10.
So we multiply the numerator and denominator
of 3/5 by 2 to get the equivalent fraction 6/10.
Since 6/10 is written as the decimal 0.6,
3/5 must be equivalent to 0.6.
