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
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
