14. B
15. 20

Step-by-step explanation:
13. 80-50=30, 80:50 = 8:5
14. 1+2+5=8
= 120/8
= 15
then 15 multiply by 2 the answer is 30 because the whole ratio is 15:30:75
15. just use proportion
1:50=n:1000
1/50 = n/1000
50n = 1000
50 50
n = 20
16. For every 3 newspapers that Ben sells, Roy sells 5 so 3:5, then,
Ben sold 15 newspapers, then we should express as n the number of newspapers sold by Roy, thus 15:N
therefore, 3:5 = 15:N
