Question

22/30
45/125
150/32

Answer 1

these are terminating or not terminating decimal

Answer 2

0.73333333333
0.36
4.6875

Answer 3

without divison

Answer 4

There is a rule to work out whether a decimal is terminating or not.

Answer 5

i know, just confirm my answer
1) non-terminating
2) & 3) terminating

Answer 6

The denominator has to have only powers of 2 and 5 ie \[\Large 2^a 5^b\]

22/30
45/125
150/32

Answer 7

I think of terminating rational numbers as repeating zeros. In that respect, there are no terminating rational numbers. Just saying.

Answer 8

\[\large 125 = 2^0 5^3\]
\[\Large 32 = 2^5\]
30= ... 2^5 is 32, 5^2 is 25... so, not expressible in that form.

Answer 9

@agent0smith I have not seen that rule before but it certainly makes sense. I've learned something, and for that, I am appreciative.

Answer 10

:) I only saw it/learned it recently. I had to look it up to remember what it was, though.

Answer 11

so my answer is correct

Answer 12

Yes, since the denominators of the second and third can be expressed as \[\Large 2^a 5^b\]
(note that a and b must be integers)

Answer 13
