Question

2/5 + 3/4 =
(3/4)(1/3-2/4)=
(2/5)÷(7/3)=
7(- 3 + 10)-12=
2+3 [2(4+5)+2]=
8+3[4(1+2)+3(2+4)]=
​

Answer 1

Respuesta:

2/5 + 3/4 =  (8+15)/20 = 23/20

(3/4)(1/3-2/4)=  (3/4)((4-6)/12) = (3/4)(-2/12) = (3/4)(-1/6) = (-3/24)

(2/5)÷(7/3)=  (2/5)(3/7) = (6/35)

7(- 3 + 10)-12=  7 (7) - 12 = 49 - 12

2+3 [2(4+5)+2]=  5 [2(9)+2] = 5 [20] = 100

8+3[4(1+2)+3(2+4)]= 11 [4 (3)+3(6)] = 11 [12+18] = 11 [30] 330
