Answer: 0
Step-by-step explanation:
Let
x-------------> <span>original price of the skates
we know that
15% of x is </span><span>$19.50
so
0.15x=19.50---------> x=19.50/0.15-----------> x=$130
the answer is
the </span>original price of the skates was $130<span>
</span>
3. yes because 15 divided by 5 and 27 divided by 9 both result in the same answer; 3.
4. No because 3/4 is not a whole number, while 4/3 is. For this to be an equivalent ratio, the second number would have to be something like 6/8.
