Answer:
50
Step-by-step explanation:
3/10 of x is 15, which means that 1/10 of x must be 5 because 15/3 = 5.
Now we can multiply 5 x 10, which is 50, so we know that x is equal to fifty
=15
Furthermore, you can convert "three" to "3" and "tenths" to "10" and then the equation and answer is:
3/10 x 15 = 4.50
