If a number is not divisible by 10 then itis not divisible by 5?
It's false because we have numbers that is divisible by 10 but not divisible by 5 and vice versa, we have numbers that is divisible by 10 but not divisible by 5.
Are all numbers that are divisible by 5 are also divisible by 10?
Yes, all numbers that are divisible by 5 are also divisible by 10. This is because 10 is a multiple of 5, meaning it can be divided evenly by 5. Therefore, any number that can be evenly divided by 5 can also be evenly divided by 10.
Can all numbers that are divisible by 5 also be divisible by 10?
No. 15 is divisible by 5.
Are all numbers divisible by 10 also divisible by 5?
Yes, since 10 is divisible by 5. Likewise, every number which is divisible by 9 is also divisible by 3.
A number is chosen at random from the first 10 whole number What is the probability that it is not exactly divisible by 3?
the first 10 whole numbers are numbers 1 to 10 and in those numbers only 3 numbers are divisible by 3 in which 3, 6 and 9 therefore the probability of from those figures that the numbers won't be divisible by 3 is 7/10 or 70%.
