2 and 1/4 over x=7/10 over 4/9
%282%281%2F4%29%29%2Fx+=+%287%2F10%29%2F%284%2F9%29

%289%2F4%29%2F%28x%2F1%29+=+%287%2F10%29%2F%284%2F9%29........multiply outer and inner terms on each side

9%2A1%2F%284%2Ax%29+=+7%2A9%2F%2810%2A4%29

9%2F4x+=+63%2F40...............cross multiply

9%2A40+=+63%2A4x

360+=+252x

x+=+360%2F252

x+=+1.43
