Question

use distributive property of multiplication over addition of each of the following
a) -2/3x(4/7+2/9).
b) 3/6x{(-9/11)+(5/-22)}​

Answer 1

Answer:

Step-by-step explanation:

a)

1  4/7 + 2/9 =        50/63

2  -2/3 x 50/63 =       -108/189

b)

1  -9/11 + 5/-22 = 1  1/22  that is a whole number and a fraction not 11/22

2 3/6 x 1  1/22 = 23/44

other way using the distributive property  

a)

1     -2/3 x  4/7 = -8/21

2     -2/3 x 2/9  = -4/27

3      -4/27 + -8/21 = -100/189

b)

1  3/6 x  -9/11 = -9/22

2  3/6 x 5/-22 = -5/44

3        -5/44 + -9/22 = -23/44
