e) 5/6-3/4 7/12+1/3 =

f) 2-1/2 /3+1/3=

Answer 1

Respuesta:

a) (2/3)(3/4)+5/6 = 6/12 + 5/6

= 3/6 + 5/6

= 8/6

= 4/3

b) 3/8+(2/3)(6/10)+(-7/20) = 3/8+12/30-7/20

= (45/120)+(48/120)-(42/120)

= 93/120 - 42/120

= 51/120

c) 5/9+(-3/8)÷(3/11) = 5/9+(-33/24)

= 40/72 + (-99/72)

= 40/72 - 99/72

= 59/72

d) 5/12÷3/4-4/5 = 20/36 - 4/5

= 5/9 - 4/5

= 25/45 - 36/45

= -11/45

e) 5/6-(3/4)(7/12)+1/3 = 5/6-21/48+1/3

= 80/96-42/96+32/96

= 112/96-42/96

= 80/96

= 10/12

= 5/6

(2-1/2) / (3+1/3) = (4/2-1/2)/ (9/3+1/3)

= (3/2)/(10/3)

= 9/20
