The quotient of a number divided by 9 is the same as the remainder. The remainder is 15. The prime number is () fast! Today,

The quotient of a number divided by 9 is the same as the remainder. The remainder is 15. The prime number is () fast! Today,

The quotient of a number divided by 9 is the same as the remainder, which is 15,
X / 9 = 15 more than 15
X=9*15+15
X=150

It is proved that the remainder can only be 1 or 19 when any prime square greater than 5 is divided by 30

There are only the following forms of prime numbers greater than 5. Calculate the square of them
30k+/-1--> 30m+1
30k+/-7--> 30m+49-->30m'+19
30k+/-11 -->30m+121-->30m'+1
30k+/-13-->30m+169--->30m'+19
Therefore, the conclusion is valid

The ratio of the smallest prime to 6 and the ratio of 1 / 2 to X are equal

The smallest prime number is 2
So 2:6 = 1 / 2: X
2X = 6 × 1 / 2
2x=3
x=3÷2
x=1.5

When X: (), the ratio of 1:33 is exactly the minimum prime

The minimum prime is 2
1/33：x=2
That is, x = (1 / 33) / 2 = 1 / 66
I hope it can help you

When x = (), the ratio of 1 / 6: X is the smallest prime

1/12

In a scale, the product of two external terms is the smallest prime number, one internal term is six seventh, and the other internal term is?
Make it clear that in an hour, I will cancel it

The smallest prime number is 2, which means that the product of two external terms or two internal terms is 2
If one internal term is 6 / 7, then the other internal term is divided by 2, 6 / 7 = 7 / 3
The other internal term is 7 / 3
