Prime numbers are: 2 3 5 7 Composite numbers are: 4 6 8 9 10 So the ratio is: 4 to 5
if the numbers are from 1 - 9 then the ratio of even to odd is 4:5 (2, 4, 6 & 8 are even, 1, 3, 5, 7 & 9 are odd)
The ratio of 5 and 7 8 and 9 12 and 18 85 and 170 is 5:7/8:9/12:18/85:170.
4 + 5 = 9, 4/9 x 1800 = 800, 5/9 = 1000
Answer: 28/45 7/9(4/5) is the same as 7(4)/9(5). 7(4) = 28 and 9(5) = 45, so the answer is 28/45.

It is 5 : 9.
Number of primes = 4 Number of composites = 5 Ratio of primes to composites = 4 : 5
The ratio of 5 and 7 8 and 9 12 and 18 85 and 170 is 5:7/8:9/12:18/85:170.
4 + 5 = 9, 4/9 x 1800 = 800, 5/9 = 1000
Answer: 28/45 7/9(4/5) is the same as 7(4)/9(5). 7(4) = 28 and 9(5) = 45, so the answer is 28/45.
4/7 = 0.57145/9 = 0.5555so 4/7 is not equal to 5/9
45/63 45 ÷ 9 = 5 63 ÷ 9 = 7 so 45/63 = 5/7; 5 to 7; 5:7
The LCM of 4, 9, 5, and 7 is 1,260.
35:45 ratio can be simplified by dividing both numbers by 5 to get 7:9 ratio.
8 - (9 ÷ (5 + 4)) = 7
