Oh, dude, it's like super easy. To write "nine increased by a number b," you just write it as 9 + b. Yep, that's it. Just add 9 and b together and you're good to go. Math can be chill sometimes, right?

5 times b
Yes. A rational number is one that you can write as a fraction a/b, with integers a and b (b not equal to zero). For a whole number, set b = 1. For example, 5 = 5/1, so it is a rational number.
You can use arrows to show that one number is less than another: if a is less than b, you can symbolize that as a<b. If a is greater than b, you can write it as a>b.
b/12-11=-5
