Answer 1

Respuesta:

(a) 9/7

(b) 75/44

(c) 205/66

(d) 51/20

(f)

(h) 27/22

Explicación paso a paso:

(a) para dividir fracciones se multiplica en Cruz

[-3/7]÷4/12 =(-3×12)/(7×4) = -36/28

simplificando queda 9/7

(b)

15/11÷4/5 =(15×5)/(11×4) = 75/44

(c)

41/3÷22/5= (41×5)/(3×22)= 205/66

(d)

17/5÷4/3=(17×3)/(5×4)=51/20

(f)

[-19/8]×[-12/7]=(-19×-12)/(8×7)=228/56 =57/14

(h)

[9/8×5/4]÷[1/4×11/3]

[(9×5)/(8×5)]÷[(1×11)/(4×3)]

(45/40)÷(11/12)

(9/8)÷(11/12)

(9×12)/(8×11)

108/88 =27/22

Answer 2

Respuesta:

a) (-3/7) ÷4/12

-3/7 × 12/4

-3/7 × 3 = -9/7

b) 15/11÷4/5

15/11 × 5/4 = 75/44

c) (12/5×7/4) × 3/2  

12 × 7 × 3/5 × 4 × 2 = 252/40 = 63/10

d) (9/8×5/4) ÷ (1/4×11/3)  

(9 × 5/8 × 4) ÷ (1 × 11/4 × 3) = 45/32 ÷ 11/12

45 × 12/32 × 11 = 540/352 = 135/88
