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.
Do the multiplication. Select the greater number.
a positive number is always greater than a negative 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.
If the top number is larger than the bottom number, it is greater than 1.
