Answer:
11/70
Step-by-step explanation:
consider ther are 40 boys and 30 girls (because 40:30 = 4:3) therefore total no of students is equal to 40+30=70. Now calculate the number of students having blue eyes. 20% of 40 is 8 (for boys) and 10% of 30 is 3 (for girls) so there are 8+3=11 number of students having blue eyes. now the ratio of number of students having blue eyes to the total number of students is 11/70
