Divide 100 to 56 = 56/100= 0.56 then you wanna times it by 50 so then it would be.56x50=28
20%=0.2
14*0.2 = 2.8 ( $2.80 is the tip she will be giving her)
$14+$2.80 = $16.80 ( what she will be giving in total)
$20-$16.80 = $3.20 (the change she will get back)

Step-by-step explanation:
A ratio compares two quantities in terms of multiplication. For example, suppose that there are 10 boys and 15 girls in a classroom. One way, not using ratios, to compare these quantities would be to say that there are 5 more girls than boys in the classroom. To employ a ratio, we say that the ratio of boys to girls is 10 to 15, or 2 to 3. In other words, for every 2 boys in the classroom, there are 3 girls.
In your case, for every 40 boys, there are 20 girls. if we simplify this all the way down, we can get 2 to 1.
All of the following are ratios that apply to your question:
40 to 20
20 to 10
10 to 5
4 to 2
2 to 1

2 x 9 = 18 so 5 x 9 = 45 so for every 18 gray chips there are 45 pink chips. Also 2/5 is equivalent to 18/45
