divide the number in the denominator you are coverting to which is 16 in problem 1), by the number in the denominator you are converting from which is 4 in the first problem. Take that answer which is 4(16/4) and multiply it by the numerator of the number you are converting from which is 3. So 3(4)=12. Now place that value over the denominator of the number your coverting to which is 16. Final answer 12/16

I will do number 3 also
:
5/6 to x/30 divide 30/6=5... 5(5)=25..so 25/30 is the answer

Convert to equivalent fractions:
1) 3%2F4+=+x%2F16 Multiply both sides by 16.
3%2816%29%2F4+=+x Simplify the left side.
%283%2A4%2Across%284%29%29%2Fcross%284%29+=+x Cancel as indicated.
12+=+x, so...
highlight%283%2F4+=+12%2F16%29
2) 1%2F12+=+x%2F48 Multiply both sides by 48.
48%2F12+=+x Simplify the left side.
%284%2Across%2812%29%29%2Fcross%2812%29+=+x Cancel as indicated.
4+=+x so...
highlight%281%2F12+=+4%2F48%29
3) 5%2F6+=+x%2F30 Multiply both sides by 30.
%285%2A30%29%2F6+=+x Simplify the left side.
%285%2A5%2Across%286%29%29%2Fcross%286%29+=+x Cancel as indicated.
25+=+x so...
highlight%285%2F6+=+25%2F30%29
4) 3%2F8+=+x%2F64 Multiply both sides by 64.
%283%2A64%29%2F8+=+x Simplify the left side.
%283%2A8%2Across%288%29%29%2Fcross%288%29+=+x Cancel as indicated.
24+=+x so...
highlight%283%2F8+=+24%2F64%29
