In a class of 65 students, 30 students say their favorite color is blue, 20 say their favorite color is red, and the rest say their favorite color is yellow.
1.What is the ratio of the students whose favorite color is red to those whose favorite color is yellow?
A.4:2
B.8:2
C.4:3
D.6:3
[tex]\small \mathbb{ANSWER:}[/tex]
SOLUTION:
In this problem,we have two steps.There are the following:
STEP 1:
Add 30 and 20 as the given number on the two favorite color.
Therefore, the sum is
After finding the sum of the two given numbers minus 65 and 50.
Hence,the number of the favorite color is yellow is 15.
STEP 2:
Try to reduce the further with the greatest common factor (GCF).
The GCF of 20 and 15 is 5
Divide both terms by the GCF, 5
20÷5 =4
15÷5 = 3
The ratio 20 : 15 can be reduced to lowest terms by dividing both terms by the GCF = 5 :
Therefore,
20:15 = 4:3
