Question

1) Hallar el valor de "A + B"

​

Answer 1

Respuesta:

A = (((1/2)+(1/3))/(1/4)) ; 1/2 = 3/6

A = (((3/6)+(1/3))/(1/4)) ; 1/3 = 2/6

A = (((3/6)+(2/6))/(1/4))

A = (((3+2)/6)/(1/4))

A = ((5/6)/(1/4)).

A = ((5×4)/(6×1))

A = 20/6

A = (20÷2)/(6÷2)

A = 10/3

B = (((1/7)+(1/5))/(1/3)) ; 1/7 = 5/35

B = (((5/35)+(1/5))/(1/3)) ; 1/5 = 7/35

B = (((5/35)+(7/35))/(1/3))

B = (((5+7)/35))/(1/3))

B = ((12/35)/(1/3))

B = (12×3)/(1×35)

B = 36/35

" A+B " :

A = 10/3 y B = 36/35

" A+B " = (10/3)+(36/35) ; 10/3 = 350/105)

" A+B " = (350/105)+(36/35) ; 36/35 = 108/105

" A+B " = (350/105)+(108/105)

" A+B " = ((350+108)/105)

" A+B " = 458/105

R// El valor de calcular " A+B " es 458/105 .
