$( \frac{3}{4} + \frac{5}{3} ) - ( \frac{5}{3} - \frac{3}{2)}$
​

Answer 1

Respuesta:

(3/4+5/3)-(5/3-3/2) = 9/4

(3/4+5/3)-(5/3-3/2) ; 3/4 = (3×3)/(4×3) = 9/12

= (9/12+5/3)-(5/3-3/2) ; 5/3 = (5×4)/(3×4) = 20/12

= (9/12+20/12)-(5/3-3/2)

= ((9+20)/12)-(5/3-3/2)

= (29/12)-(5/3-3/2) ; 5/3 = (5×4)/(3×4) = 20/12

= (29/12)-(20/12-3/2) ; 3/2 = (3×6)/(2×6) = 18/12

= (29/12)-(20/12-18/12)

= (29/12)-((20-18)/12)

= (29/12)-(2/12)

= (29-2)/12

= 27/12

= (27÷3)/(12÷3)

= 9/4
