You can put this solution on YOUR website!
5b+15
______
7b+21
Start with the numerator;
5b+15;
to factorout the 5,
5(b+3)
Now the denominator;
7b+21
facot out the 7;
7(b+3)
now you have;
5%28b%2B3%29%2F7%28b%2B3%29
Now you can cancel out the (b+3); and your answer would be;
5%2F7
Glad to hear your coming back, GOOD LUCK!!!
