3. See the math:
Do the division, and see if there is a remainder.
No other number except 1 divides evenly into both 4 and 5, so 4/5 is in simplest form
if all the digits add up to a number divisible by 3 like 195 195= 1+9+5= 15...15/3=5 so it is divisible by 3
In the decimal numbering system, if the number ends in 0 or 5 it is evenly divisible by 5. If it ends in any other number it is not.
a positive number is always greater than a negative number
Do the multiplication. Select the greater number.
No. You can tell this by looking at the last number 5 goes evenly into numbers ending in 0 and 5. Five does not go evenly into 7.
nothing tell me the answer
Multiply them out.
If the last three digits can be divided evenly by 8, then so can the entire number
A whole number is evenly divisible by 10 only if its last digit is a zero.
It is easy to tell that 4,567,278 is a composite number because it is an even number, meaning it is divisible by 2. Any even number greater than 2 has factors other than 1 and itself, confirming that it has multiple divisors. Additionally, a quick check of its divisibility by 2 reveals that it can be divided evenly, making it composite.
