Answer 1

Step-by-step explanation:

a) Through commutative property.

LHS:

1. 4+(-3/4 + - 2/5)
2. 4+(((-3*5)+(-2*4))/20)
3. 4+-23/20
4. 57/20

RHS:

1. (4+-3/4)+ -2/5
2. (((4*4)+-3)/4)+ -2/5
3. 13/4 + - 2/5
4. ((13*5)+(-2*4))/20
5. 57/20

LHS=RHS

b) Through distributive property.

LHS:

1. -7/15(2/3 + - 5/12)
2. -7/15(((2*4)+ - 5)/12)
3. -7/15 *1/4
4. -7/60

RHS:

1. -7/15*2/3 + - 7/15*-5/12
2. -14/45 + 7/36
3. ((-14*4)+(7*5))/180
4. -21/180
5. -7/60

LHS=RHS
