Step-by-step explanation:
Count of numbers up to 50 = 50
Prime numbers up to 50 :
{2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47}

Hence, ratio of prime numbers to all numbers ;
15 : 50
3 / 10
Answer:
see explanation
Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v = 
← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 = 
( multiply both sides by 5 )
45 = k
v = 
← equation of proportion
When w = 4 , then
v = 
= 11.25
