Given:
Jan makes a party punch that requires 2 gallons of orange juice for every 1/2 (0.5) gallon of lemonade.

Jan makes a party punch by mixing orange juice and lemonade in = 2:0.5
Matt makes a party punch by mixing orange juice and pineapple juice in = 3:2
Let ratio be
To find how many gallons of orange juice would Jan use,
By dividing both sides by 2.5
,
Jan use gallons of orange juice to make 10 gallons of punch,
Similarly, to find how many gallons of orange juice would Matt use,
By dividing both sides by 5
Matt use gallons of orange juice to make 10 gallons of punch,
Now, to find how many more gallons of orange juice would Jan use than Matt,
Jan use gallons of orange juice to make 10 gallons of punch - Matt use gallons of orange juice to make 10 gallons of punch
