Step-by-step explanation:
First you divide the numerator and the denominator by 10, it leaves you with 1500/21 , now you again divide the numerator and denominator by 3 and you get 500/7.
Remember, you ought to divide the numerator and the denominator only by the numbers which are their common factors or in a more easier way, you only divide them by a number which divides them both simultaneously.
Step-by-step explanation:

A + b = 87
a = b - 11
b - 11 + b = 87
2b - 11 = 87
2b = 87 + 11
2b = 98
b = 98/2
b = 49 <===
a = b - 11
a = 49 - 11
a = 38 <===
