Kemudian mencari nilai dari a plus b plus c plus d,

table attributes columnalign right center left columnspacing 0px end attributes row cell a plus b plus c plus d end cell equals cell 1 over 8 plus 5 over 8 plus 1 half plus 17 over 8 end cell row blank equals cell 1 over 8 plus 5 over 8 plus 4 over 8 plus 17 over 8 end cell row blank equals cell fraction numerator 1 plus 5 plus 4 plus 17 over denominator 8 end fraction end cell row blank equals cell 27 over 8 end cell row blank equals cell 3 3 over 8 end cell end table


Jadi, nilai dari a plus b plus c plus d adalah table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell 3 3 over 8 end cell end table.
