Firstly multiply by 10
Secondly divide by 2
Example: 5 x 6
6 x 10 = 60
60 / 2 = 30 = 5 x 6
There is no work. The only prime number ending in 5 is 5.
The number is divisible by 5 then its end is either 0 or 5 The number is divisible by 9 then the sum of its digits is divisible by 9 If the number is divisible by 5 but not by 10 then it means that the number is divisible by 5 but not by 2, thus it's not an even number. The number is not even so it ends with 5 So the number is written a5a5 or aa55 or 5aa5. a+5+a+5 = 2 x a+10 which must be divisible by 9 if a = 1 then is doesn't work if a = 2 then is doesn't work if a = 3 then is doesn't work if a = 4 then 4545 or 4455 or 5445 are ok if a = 5 then is doesn't work if a = 6 then is doesn't work if a = 7 then is doesn't work if a = 8 then is doesn't work if a = 9 then is doesn't work
It doesn't work
If you are trying to work out the decimal form of a fraction, such as 4/5, divide the numerator (top number) by the denominator (bottom number). 4/5 = 0.8
you work out 5% and minus 1%
Multiply the number by 3/5 or 0.6
If the rules for 2 and 3 work, the number is divisibale by 5.
No. Any number that is divisible by 10 is divisible by 5. It doesn't work the other way.
A number model is something that shows the work u did. For example 5+6=11 that is a number model
52•(-5)=52•5=260 since a positive number times a negative number equals a negative, the answere is -260
You work out 1% of the number (divide by 100) and then work out 5% of the number (divide by easier option to work out 6%: work out 1% (divide by 100) (move 2 places back) then times by 6
example of how to find the square root= the number is 25 so the answer is 5 because 5 x 5=25
