1/8:2/3:: 75:x = %281%2F8%29%2F%282%2F3%29+=75%2Fx
move x to the left
%281%2F8%29%2F%282%2F3%29%2Ax+=75%2F1
move 2/3 to the right
%281%2F8%29%2Ax+=75%2F1%2A%282%2F3%29
%281%2F8%29%2Ax+=25%2F1%2A%282%2F1%29
%281%2F8%29%2Ax+=25%2A2
x%2F8+=50
move 8 to the right
x+=50%2A8
x=400
result is 400

%281%2F8%29%2F%282%2F3%29+=+75%2Fx

%281%2F8%29+%2A+x+=+%282%2F3%29+%2A+75 ------ Cross-multiplying

x%2F8+=+50 

x+=+8%2850%29 -------- Cross-multiplying
