This question is like a proportion. a:b is 4:5 Which means a is 4, and b is 5. And now, the question says b equals 585. Since, b is 5 from the first, one, what do you have to multiply by to get to 585? 117. So, multiply 117 by 4, to get a value of new A. 117X4. You get an answer 468.

If the ratio a:b is 4:5 and b=585, then this can be represented by: a/585 = 4/5.
a/585 = 4/5
(a)(5) = (585)(4) ---> Cross-Multiply
5a = 2340 ---> Simplify
a = 468 --->Divide both sides by 5.
a is 468.
Check answer by dividing 468 by 585 and 4 by 5. Both are equal to 0.8, so you know that they're the same.

a/b=4/5 so a = 4/5*b
so a= 4/5*585 =468

a/b = 4/5
If b = 585, then a = 585 * 4 /5 = 468

Divide 585 by 5, take that answer and multiply it to your 4, that should give the right answer.

4 to 5=a to 585
simplify you will get:
4 to 1=a to 117
4*117 is 68 which is the answer.
simple enough
