Answer:
1:4
Explanation:
30%=
18%=
<em>Rewrite the given information:</em>
<em>Multiply by 100 throughout:</em>
30(B -A)= 18(B+A)
<em>Divide by 6 throughout,</em>
5(B -A)= 3(B +A)
<em>Expand</em>
5B -5A= 3B +3A
<em>Bring</em><em> </em><em>A</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em> </em><em>and</em><em> </em><em>B</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>another</em><em>:</em>
5B -3B= 5A +3A
<em>Simplify</em>
2B= 8A
<em>Divide by 2 throughout:</em>
B= 4A
Now, we have to find the ratio of A to B.
B= 4A
<em>Divide by 4 throughout:</em>
A =
<em>Divide by B on both sides:</em>
Thus, A:B= 1:4
