Answer:
About 2 students own a pet iguana
Step-by-step explanation:
Step 1
Determine the expression for the total number of students that own pet iguanas as shown;
N=p×T
where;
N=total number of students that own pet iguanas
p=proportion of total students that own pet iguanas
T=total number of students
In our case;
N=unknown
p=0.3 % of students
T=610 students
replacing;
N=0.3% of 610
N=(0.3/100)×610
N=1.83, round up to 2 since 1.83 is closer to 2 than 1
About 2 students own a pet iguana
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Total number of marbles = 54
All marbles are red and blue
Fraction of blue = 1/3
Hence,
Number of Blue = 1/3 * 54 = 18
Hence,
Number of red = 54 - 18 = 36
Ratio of blue to total ;
18 : 54 = 1 : 3
Ratio of Red to total;
36 :54 = 2 : 3
Ratio of Red to blue :
36 : 18 = 2 : 1
Number of red = 36
