Question 151623
I'll do the first two to get you started


# 1


{{{3/4}}} Start with the first fraction.



{{{(3*2)/(4*2)}}} Multiply <font size=4><b>both</b></font> the numerator and denominator by 2 (any number will do)



{{{6/8}}} Multiply 3 and 2 to get 6. Multiply 4 and 2 to get 8. 



So {{{6/8}}} is equivalent to {{{3/4}}}



<hr>



{{{7/9}}} Start with the second fraction.



{{{(7*2)/(9*2)}}} Multiply <font size=4><b>both</b></font> the numerator and denominator by 2 (any number will do)



{{{14/18}}} Multiply 7 and 2 to get 14. Multiply 9 and 2 to get 18. 



So {{{14/18}}} is equivalent to {{{7/9}}}
