What number has 9 tens and 4 fewer ones than tens
99
The number with 15 tens and 12 ones can be calculated by multiplying the number of tens by 10 and adding the number of ones. So, 15 tens is 150 (15 x 10) and adding 12 ones gives you 150 + 12 = 162. Therefore, the number is 162.
The number with 6 tens and 11 ones can be calculated by multiplying the number of tens by 10 and adding the number of ones. Therefore, 6 tens is 60 (6 x 10) and 11 ones is 11. Adding these together, 60 + 11 equals 71. Thus, the number is 71.
There is no four digit number where the ones is twice the tens, the hundreds is five less than the ones, and the thousands is the sum of the tens and hundreds. int ones, tens, hundreds, thousands; for (thousands=1; thousands<10; thousands++) { /**/ for (hundreds=0; hundreds<10; hundreds++) { /**/ /**/ for (tens=0; tens<10; tens++) { /**/ /**/ /**/ for (ones=0; ones<10; ones++) { /**/ /**/ /**/ /**/ if (ones != 2 * tens) break; /**/ /**/ /**/ /**/ if (hundreds != ones - 5) break; /**/ /**/ /**/ /**/ if (thousands != tens + hundreds) break; /**/ /**/ /**/ /**/ printf ("dd\n", thousands, hundreds, tens, ones); /**/ /**/ /**/ } /**/ /**/ } /**/ } }

What number has 9 tens and 4 fewer ones than tens
2 tens 3 ones. 20+3

8 tens 2 ones
3 tens is equal to the number 30, and 3 ones is equal to the number 3.So, 3 tens and 3 ones is 33; and 67 minus 33 (or 67 less33) is 34.You could also look at the number 67 and see that it is 6 tens and 7 ones. Then it is easier to say "6 tens and 7 ones minus 3 tens and 3 ones = 34"because:6 tens minus 3 tens = 3 tens, and 7 ones minus 3 ones = four ones.3 tens and four ones = 34
The number with 15 tens and 12 ones can be calculated by multiplying the number of tens by 10 and adding the number of ones. So, 15 tens is 150 (15 x 10) and adding 12 ones gives you 150 + 12 = 162. Therefore, the number is 162.

The prime number between 20 and 30 whose ones digit is 7 greater than its tens digit is 23. The tens digit is 2, and the ones digit is 3, which is 7 greater than 2. Additionally, 23 is a prime number because it is only divisible by 1 and itself, with no other factors.
