Because a pair of numbers is a pair of numbers.
Factor strings are multiplication sentences. 2 x 8 = 16 3 x 4 x 5 = 60 are examples of factor strings.
Why, yes, indeed, it has! Look at the factors: x2 - 8x + 16 = (x - 4)2 = (x - 4)(x - 4). If you multiply it out, you will see that it is so. Note that ' (x - 4) ' appears twice in the factorisation. That is what we mean, by a 'repeated factor'.
To simplify, find the Greatest Common Factor between numerator and denominator, then divide both by the GCF to find the new numerator and denominator. Memorizing your multiplication tables helps make this easier.GCF of 27 and 48 is 3: 27/3 = 9. 48/3=16, so 9/16
The greatest common factor of 16 and 21 is 1. Therefore, 16/21 cannot be reduced and is already in its simplest form.
Since the numerator of the fraction is prime, and not a factor of the denominator, the proper fraction 5/16 is already expressed in its simplest form.
-8.444... = -76/9 = -8 4/9 -8.48484... = -280/33 = -8 16/33
