1/2 is equivalent to 2/4 because,
2(1/2) = 2/4
So as you can see if you multiply the numerator(top) and the denominator(bottom) by the same number, you get an equivalent fraction! In my example you can see that I multiplied both by 2.
Tell me the question and I’ll help you with it is it simplify or evalute etc.
15x^2+21x+6 that’s the answer
The answer would be theorem Side angle side (aka SAS)
