Answer:
9. Juanita's recipe.
10. Leon's recipe.
Explanation:
9. All you need to do is convert the numbers into fractions.
Juanita's recipe: 4 parts lemon, 2 parts sugar. Lydia's recipe: 5 parts lemon and 3 parts sugar. So in order to find the lemon amount in each recipe convert into this fraction:
lemon/sugar
Juanita: lemon/sugar= 4 lemon/2 sugar
Lydia: lemon/sugar= 5 lemon/3 sugar
The LCM is 6 so that is the denominator.
Juanita: 4 lemon/2 sugar= 12 lemon/6 sugar
Lydia: 5 lemon/3 sugar= 10 lemon/6 sugar
The ratio is 4:2= ?:6 and 5:3= ?:6
Juanita has 12 lemon and Lydia has 10, so Juanita has more lemons.
10. Same as number 9.
Use the fraction peanuts/pretzels because it wouldn't work if peanuts is on the bottom otherwise both Leon and Cisco's peanut amount will be the same. SO put peanuts over pretzels, so pretzels will be the denominator so we can find the peanut amount.
peanuts/pretzels
Leon: peanuts/pretzels= 3 peanuts/8 pretzels
Cisco: peanuts/pretzels= 2 peanuts/6 pretzels
The LCM is 24 so that is the denominator.
Leon: 3 peanuts/8 pretzels= 9 peanuts/24 pretzels
Cisco: 2 peanuts/6 pretzels= 8 peanuts/24 pretzels
The ratio is 3:8= ?:24 and 2:6= ?:24
Leon has 9 peanuts and Cisco has 8, so Leon has more peanuts.
