Answer:
unit rate of lemonade to cranberry juice
= 5:1
Step-by-step explanation:
A recipe for fruit punch calls for 1/2 liter of lemonada and 1/10 liter of cranberry juice
1/2 liter of lemonada= 0.5
1/10 liter of cranberry juice = 0.1
unit rate of lemonade to cranberry juice
= 0.5/0.1
unit rate of lemonade to cranberry juice
= (5*10^-1)/(1*10^-1)
unit rate of lemonade to cranberry juice
= 5/1 *(10^-1)/10^-1)
unit rate of lemonade to cranberry juice
= 5/1
unit rate of lemonade to cranberry juice
= 5:1
The unit rate of lemonade to cranberry juice is 5 : 1.
1/2 liters of lemonada are to be mixed with 1/10 litres of cranberry juice.
In ratio form this is:
1/2 : 1/10
To make it a unit rate of lamonada, you should divide both sides by the ratio of lamonada to cranberry juice in order to take lomonada's ratio to 1.
= 1/2 ÷ 1/2 : 1/10 ÷1/2
= 1 : 0.2
You then need to make the decimal a whole number by dividing both sides by the decimal:
= 1 ÷ 0.2 : 0.2 ÷0.2
= 5 : 1
The unit rate of lamonada to cranberry juice is therefore 5 : 1.
