Question

Simplify

Answer 1

to simplify this you want to get rid of the fraction on the bottom
to do this you will mutliply by 1
1 in this question shall be 30/30
multiply top and bottom by 30/30
this cancels out the 30 on the bottom
then after you finish that you will multiply by 1 again but this time it will be
6/6
then you will simplify

Answer 2

The answer is A

Answer 3

since you're dividing, you have to multiply by the reciprocal:\[\large{{{y\over6}\over{7y^2\over30}}~~~~\implies~~~~{y\over6}\times{30\over7y^2}}\]just multiply straight across giving you\[\large{30y\over 42y^2}\]now using the exponent properties, simplify \[\large{5\over 7y}\]

Answer 4

option a

Answer 5

an of course y cannot equal zero because that would make zero the denominator and the denominator cant be zero :)
