Question

(COMPLETA CON LOS NUMEROS QUE FALTAN)​

Answer 1

Vamos a completar los números que faltan resolviendo las ecuaciones

a)

(9/5) / X = -11/10

9/5 = -11/10 * X

X = (9/5) / (-11/10)

X = (9*(-11)) / (5*10)

X = -99 / 50

b)

(10/3) / X = 1

X = 3/10

c)

(13/10) * X * 15/4 = -39

[(13*15) / (10*4)]*X = -39

195 / 40*X = 39

39/8 * X = 39

X = 39 * 8/39

X = 8

d)

(-7/5)* (-3/2)*X = 2/5

(-7*-3) / (5*2) * X = 2/5

(21/10) * X = 2/5

X = (2*10) / (21*5)

X = 20 / 105

X = 4/21
