7
The ones place in odd numbers will be odd (1, 3, 5, 7, 9)
7 tens and 4 ones 5 thousandths = 74.005
2, 3, 7, 8
0.6364
The number that has 7 tens and less ones than tens is 70 minus a certain number of ones. Since there are 7 tens, which is 70, and it needs to have less than 7 ones, the possible values for the ones place are 0 through 6. Therefore, the possible numbers are 70, 71, 72, 73, 74, 75, and 76.
The prime numbers are 3 and 7 but 1 is not considered to be a prime or a composite number

We can't tell what those numbers are without spaces between them. Eliminate the ones that aren't multiples of 7, like 271, and proceed from there or re-submit the question.
No, binary numbers don't consist of ones and twos, they are ones and zeros.
