Let the incorrect answers be denoted by I.
Given the following data;
Correct answers = 45 answers
Incorrect answers = 50 - 45 = 5 answers
Ratio of correct to incorrect answers;
C : I = 45 : 5
Dividing by 5, we have;
C : I = 9 : 1

<span>The correct answer is 12/17m+30/17 yellow ribbons.
Explanation:
Setting up a proportion to represent the ratio of red to yellow, we have
r/y = 17/6.
Cross multiply:
6r=17y.
To isolate y, cancel 17 by dividing:
6r/17 = y, or (6/17)r=y.
Substituting 2m+5 for r, we have
(6/17)(2m+5)=y.
Use the distributive property:
(6/17)*2m+(6/17)*5=y
(12/17)m+30/17=y.</span>
Answer:
15 students at school
Step-by-step explanation:
So there is 50 students in total
First subtract that much with how much students have the flu
1/10 = 5/50
So 5 students have the flu
That leaves 45 students
Then subtract that much with the amount of students that are remaining are on the field trip
45 divided by 3 = 15
so 2/3 = 30/45 (they can both be multiplied and divided by 15)
so 30 of the 45 students are on the field trip
45 - 30 = 15
That means there are 15 students left over at school
