Respuesta :

Answer:

B. 3/10

Explanation:

Given the following

Fraction of student wearing purple shirts = 2/5

Fraction of students wearing gold shirts = 3/10

Required

Fraction of student wearing blue shirts

Let the total shirt be 1

Fraction of student wearing blue shirts = 1 - (2/5 + 3/10)

Fraction of student wearing blue shirts = 1 - ((4+3)/10)

Fraction of student wearing blue shirts = 1- 7/10

Fraction of student wearing blue shirts = (10-7)/10

Fraction of student wearing blue shirts = 3/10

Hence the fraction of student wearing blue shirts is 3/10
