Answer:Step-by-step explanation:( 15 + \frac{2}{3} ):Convert 15 to a fraction: ( \frac{15}{1} )Find a common denominator: ( \frac{15 \times 3}{1 \times 3} = \frac{45}{3} )Add the fractions: ( \frac{45}{3} + \frac{2}{3} = \frac{47}{3} )The sum is ( \frac{47}{3} ) or ( 15 \frac{2}{3} )( 23 - \frac{16}{8} ):Simplify ( \frac{16}{8} = 2 )Subtract: ( 23 - 2 = 21 )The sum is ( 21 )( \frac{27}{15} + \frac{28}{15} ):Add the fractions: ( \frac{27 + 28}{15} = \frac{55}{15} )Simplify: ( \frac{55}{15} = \frac{11}{3} )The sum is ( \frac{11}{3} ) or ( 3 \frac{2}{3} )( 56 - \frac{32}{10} + 1 ):Simplify ( \frac{32}{10} = 3.2 )Subtract and add: ( 56 - 3.2 + 1 = 53.8 )The sum is ( 53.8 )( \frac{63}{5} + \frac{52}{28} ):Simplify ( \frac{52}{28} = \frac{26}{14} = \frac{13}{7} )Find a common denominator: ( \frac{63 \times 7}{5 \times 7} = \frac{441}{35} ) and ( \frac{13 \times 5}{7 \times 5} = \frac{65}{35} )Add the fractions: ( \frac{441}{35} + \frac{65}{35} = \frac{506}{35} )The sum is ( \frac{506}{35} ) or approximately ( 14.457 ) \frac{715}{26} + \frac{2}{9} ):Find a common denominator: ( \frac{715 \times 9}{26 \times 9} = \frac{6435}{234} ) and ( \frac{2 \times 26}{9 \times 26} = \frac{52}{234} )Add the fractions: ( \frac{6435}{234} + \frac{52}{234} = \frac{6487}{234} )The sum is ( \frac{6487}{234} ) or approximately ( 27.72 )
