Answer = 1
The expression is given as:
[tex]\frac{20}{5(1+3)}[/tex][tex]\text{Note that 1 + 3 = 4}[/tex]The expression then becomes:
[tex]\frac{20}{5(4)}[/tex][tex]\text{Also note that 5 x 4 = 20}[/tex]The expression becomes:
[tex]\frac{20}{20}\text{ = 1}[/tex]The answer is to the simplification of the expression is 1
