Answer:
The unit rate is 6 1/4 cups of soda per cup of pineapple juice
Step-by-step explanation:
we know that
To find out the unit rate of soda to pineapple juice in the punch, divide the cups of soda by the cups of pineapple juice
so
[tex]2\frac{1}{2} :\frac{2}{5}[/tex]
Convert mixed number to an improper fraction
[tex]2\frac{1}{2}=2+\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}[/tex]
substitute
[tex]\frac{5}{2} :\frac{2}{5}[/tex]
Multiply in cross
[tex]\frac{25}{4}= 6.25[/tex]
Convert to mixed number
[tex]6.25=6+0.25=6+\frac{1}{4}= 6\frac{1}{4}[/tex]
That means
The unit rate is 6 1/4 cups of soda per cup of pineapple juice
