10 rounded to the nearest tens place is: 10. This is because the ones value is "0" so it does not round up.
Places in the decimal system are based on powers of ten. 10^2 = hundreds 10^-2 = hundredths 10^1 = tens 10^-1 = tenths 10^0 = ones Since zero doesn't have a negative counterpart, the ones column stands alone.
5 and 10
3 is the ones digit in 4903. Since 3 is less than five, the ones digit becomes zero when 4903 is rounded to the nearest 10. 4903 to the nearest 10 is 4900.0 is the tens digit in 4903. Since 0 is less than five, the ones and tens digit are each 0 when 4903 is rounded to the nearest 100. 4903 to the nearest 100 is 4900. 9 is the hundreds digit in 4903. Since 9 is five or more, the thousands digit next to it is increased by one and the hundreds, tens, and ones digits are each zero. 4903 to the nearest 1000 is 5000.
It is the tens' place.
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); /**/ /**/ /**/ } /**/ /**/ } /**/ } }
The general function is:1. y = a*x+bb is irrelevant and we can be removed2. y = a*xlets split x into ones and tens3. x = tens*10 + ones /e.g. 23 = 2*10 + 34. p1 = Multiplier of the onesp2 = Multiplier of the tens5. y = tens*10*p2 + ones*p1 /according to the question6. x*a = tens*10*p2 + ones*p1 /according to 2.7. (tens*10 + ones)*a = tens*10*p2 + ones*p1 /according to 3.8. tens*10*a + ones*a = tens*10*p2 + ones*p1 /regroup9. tens*10*a - tens*10*p2 + ones*a - ones*p1 = 0 /regroup10. tens*10*(a-p2) + ones*(a-p1) = 0 /regroup11. assuming "tens" and "ones" are not 0 then (a-p2) and (a-p1) must be 012. a-p2 = 0a-p1 = 013. a = p2a = p114. a = p1 = p2the answer is: when the Multipliers of ones and tens are equal then the product is called a.

A 0 in the tens place of any number represents 0 times 10, which is 0.
660. remember when rounding to the nearest ten your lowest non zero number will be in the tens place and you will look at the ones place to decide whether or not to round up. If the ones place is 5 or above, round up in the tens place. If the ones place is 0-4 keep the remaining tens place number.
Let's take, for example the number 10. The '1' is the tens place, and the '0' is the ones place (also refereed to as the 'unit').
