Ratios
A ratio is a relation between two quantities and it's calculated as a division. For example, the ratio between 8 and 4 is 8 / 4 = 2.
Xavier and Alicia share some money in the ratio 3:5. This means for each $3 of Xavier's, there are $5 of Alicia's. It's expressed as a fraction:
[tex]\frac{3}{5} \text{ or } \frac{5}{3}[/tex]
a
It's given Xavier gets $75. Alicia gets more than that, so we multiply:
[tex]\$75*\frac{5}{3}=\$125[/tex]
Thus, Alicia gets $125
b
Xavier and Alicia share a total of $75+$125 = $200
