Without the image, I assume the two semicircles are on each end of the rectangle.
Rectangle; A = lw
A = 98 x 76
A = 7,448 square meters
Put the two semicircles together to form a circle; A = π

A = (3.14)(

)
A = 3.14 x 76 = 5,776 square meters
7,448 + 5,776 = 13,224 square meters
Well he earned $50 this week and $25 the following week, so 2/5 of $75 is $30
Fraction of students enrolled in Chinese = 
Fraction of students enrolled in French = 
Fraction of students enrolled in Spanish =
Solution:
Total number of students = 51 + 33 + 42
= 126
Number of students enrolled in Chinese = 51
Fraction of students enrolled in Chinese

Fraction of students enrolled in Chinese = 
Number of students enrolled in French = 33
Fraction of students enrolled in French

Fraction of students enrolled in French = 
Number of students enrolled in Spanish = 42
Fraction of students enrolled in Spanish

Fraction of students enrolled in Spanish =
You would use 2 number lines to compare fractions because if you were trying to see which fraction was larger than you would use a number line.
The answer is B. First turn all the results from the spelling competition into fractions (or ratios).
Megan: 45/50 = 9/10
Justin: 27/30 = 9/10
Fernando: 84/120 = 7/10
Then, use this information to find which answer is correct.
Have a nice day! :)
