{{{5&1/2}}}{{{"÷"}}}{{{4&3/5}}}

Change each mixed number to an improper fraction 
by this rule: {{{A}}}{{{B/C)}}}{{{""=""}}}{{{(CxA+B)/C}}}

{{{(2x5+1)/2}}}{{{"÷"}}}{{{(5x4+3)/5}}}

Do the multiplications in the numerators:

{{{(10+1)/2}}}{{{"÷"}}}{{{(20+3)/5}}}

Do the additions in the numerators:

{{{11/2}}}{{{"÷"}}}{{{23/5}}}

Invert the second fraction and change the division symbol to a 
multiplication symbol:

{{{11/2}}}{{{"x"}}}{{{5/23}}}

Multiply the two numerators,  11x5=55
Multiply the two denominators,  2x23=46

Answer as improper fraction:  {{{55/46}}}

Change to a mixed number by this rule:

1. Divide denominator into numerator

   <u> 1</u>
46)55
   <u>46</u>
    9

2. Use rule  {{{QUOTIENT+REMAINDER/DIVISOR}}}

Answer:  {{{1&9/46}}}
