What is the difference between 126 1/4 and 78 2/3
we have the numbers $126\frac{1}{4}$ and $78\frac{2}{3}$

we have to find the value of $126\frac{1}{4}-78\frac{2}{3}$

simplify: $\frac{1+126\times4}{4}-\frac{2+78\times3}{3}$

multiply: $\frac{1+504}{4}-\frac{2+234}{3}$

add: $\frac{505}{4}-\frac{236}{3}$

find like denominators: $\frac{505\times3}{4\times3}-\frac{236\times4}{3\times4}$

multiply: $\frac{1515}{12}-\frac{944}{12}$

combine fractions: $\frac{1515-944}{12}$

subtract: $\frac{571}{12}$

simplify: $\boxed{47\frac{7}{12}}$
