Both A and D seem like terminating decimals..

A = 1.89

D = 576/100 = 5.76

Which of the following fractions has a decimal equivalent that is a terminating decimal?

A.10/189
B.15/196
C.16/225
D.25/144
E.39/128

I think this was the original question

If you can see a patern , the denominators of A,B,C and D are a square of a number.

E it is.

Hi,

Could you explain what the denominator being a sqaure of something has to do with terminating decimals?

Thanks

I don't think this is true.

1/256 results in terminating decimal.
The main point I think is when you see a prime factor (except 2 and 5) in the denominator then it will NOT be a terminating decimal.
A - 189 = 3 * 3 * 3 * 7
B - 196 = 2 * 2 * 7 * 7
C - 225 = 3 * 3 * 5 * 5
D - 144 = 2 * 2 * 2 * 2 * 3 * 3
But E - 128 = 2 * 2 * 2 * 2 * 2 * 2 * 2

Also 189 is not a perfect square.

Wow, nice tip, Dahiya. Thanks! Does this hold true for all fractions?

I think so. But be careful about the denominator too. For example

Though 56 = 2*2*2*7 but 14/56 is terminating because 14/56 can be reduced to 1/4.

thanks for the tip! however, i think you mean the numerator...

I get A C and D as answers.

Term decimal has either 2, 5, or 2 and 5 in the denominator.

So....???....

Ah thx. This makes sense now

forgot to add this bit on my original post. 2, 5, or 2 and 5 must be in the bottom with NO other numbers!
