What is 280 dived by 140?

Answer 1

We have: 280 / 140 = ???

The first thing we can notice is both numbers end in zero, so we can drop one zero on each number and end up with:

280/140 = 28 / 14

If we look at the numbers, we can see they are both divisible by seven, noted below:

28/14 = (7 x 4) / (7 x 2)

The 7's therefore cancel out and we are left with four over two:

(7x4)/(7x2) = 4 / 2

At this point you either realize the answer is two or you note that both numbers are even, so half both numbers again:

4/2 = 2/1 = 2

So the answer is: 280/140 = 2

280/140=2 because remove the zeros so it's 28/14 which equals 2. To recheck if you're correct do 140*2=280.
