Explicación paso a paso:
Este signo "*" es igual al "x" de la multiplicación.
Este signo "/" es igual al "÷" de la división.
Ejercicio 1
1) a + b
(4/5)+(5/6)= ((4*6)+(5*5))/(5*6)= (24+25)/30= 49/30
2) a - b
(4/5)-(5/5)= ((4*6)-(5*5))/(5*6)= (24-25)/30= -1/30
3) h + c
(-8/2)+(-5/4)= ((-8*4)+(-5*2))/(2*4)=(-32-10)/8= -42/8= -21/4
4) h - c
(-8/2)-(-5/4)= ((-8*4)-(-5*2))/(2*4)= (-32+10)/8= -22/8= -11/4
5) c + d
(-5/4)+(2/5)= ((-5*5)+(4*2))/(4*5)= (-25+8)/20= -17/20
6) f - d
(7/9)-(2/5)= ((7*5)-(9*2))/(9*5)= (35-18)/45= 17/45
7) c + g
(-5/4)+(-2/9)= ((-5*9)+(-2*4))/(4*9)= (-45-8)/36)= -53/36
8) f - g
(7/9)-(-2/9)= ((7-(-2))/9= (7+2)/9= 9/9= 1
Ejercicio 2
1) a * b
(4/5)*(5/6)= (4*5)/(5*6)= 20/30= 2/3
2) g * c * h
(-2/9)*(-5/4)*(-8/2)= (-2*(-5)*(-8))/(9*4*2)= -80/72= -10/9
3) c * d
(-5/4)*(2/5)= (-5*2)/(4*5)= -10/20= -1/2
4) a * g
(4/5)*(-2/9)= (4*(-2))/(5*9)= -8/45
5) b ÷ f
(5/6)÷(7/9)= (5/6)*(9/7)= (5*9)/(6*7)= 45/42
6) h ÷ c
(-8/2)÷(-5/4)= (-8/2)*(-4/5)= (-8*(-4))/(2*5)= 32/10= 16/5
7) c ÷ d
(-5/4)÷(2/5)= (-5/4)*(5/2)= (-5*5)/(4*2)= -25/8
8) c ÷ g
(-5/4)÷(-2/9)= (-5/4)*(-9/2)= (-5*(-9))/(4*2)= 45/8
