You would put this into a fraction
so for the salad
and for the fruit
cross multiply and
1. salad: 20% = 115 students
2. Fruit: 24% = 138 students
3z - 7 = 14 |add 7 to both sides
3z = 21 |divide both sides by 3
z = 7
108 .
explanation : 36 x 3 = 108

Answer:
7/12 of the students
Step-by-step explanation:
So first you would need to get your fractions to have the same denominator. When your trying to get your fractions to get the same denominato. You must multiply both the numerator and denominator.
The most common denominator from 1/4 and 1/3 is 12. So you multiply both the numerator and denominator of 1/4 by 3. So then your new fraction is 3/12. Now you multiply 1/3, both numerator and your denominator by 4. Then your new fraction is 4/12. So The last step is to add both of your numerators. Never add the denominators together. And at last you have your answer. 7/12.

Answer:
$67,200
Step-by-step explanation:
The amount if interest is given by the formula ...
I = Prt
where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.
P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025
P = $67,200
The amount invested was $67,200.
