Answer:
90
Step-by-step explanation:
Find common denominators. Note that what you multiply to the denominator (bottom number of the fraction), you must also multiply to the numerator (top number of the fraction).
In this case, you are multiply 10 to both the numerator and denominator, as:
100/10 =10
Multiply 10 to the numerator:
? = 9 * 10
? = 90
90 is your answer.
