Question

Use commutative and distributive properties to simplify 4/5*-3/8-3/8*1//4+19/20

Answer 1

Answer:

89/160

Step-by-step explanation:

(4/5)(-3/8)-(3/8)(1/4)+19/20

= (4/5)(-3/8) + (-3/8)(1/4)  + 19/20

= (-3/8)(4/5) + (-3/8)(1/4)  + 19/20

= (-3/8)(4/5 + 1/4)  + 19/20

= (-3/8)(21/20) + 19/20

=  - 63/160  + 19/20

= (1/160)(-63 + 152)

= 89/160

= 0.55625

(4/5)(-3/8)-(3/8)(1/4)+19/20 = 89/160
