Explanation<span>:
Decimals deal with powers of 10, such as 10, 100, 1000, etc. We can change this to a power of 10 by dividing both top and bottom by 2; this will give us 100 in the denominator.
77/2=38.5, so we have 38.5/100.
Dividing by 100 is the same as moving the decimal two places to the left, so we have 0.385.</span></span>
