Question

Evaluate b−c+d

if b=−3/4
, c=0.4
, and d=1/2
. Write in simplest form.

Answer 1

-13/20 or -0.65

Explanation:

The equation is:

b - c + d

Insert all the value of b, c and d into the above equation:

b - c + d = -3/4 - 0.4 + 1/2

Solve the above inserted value:

= -3/4 - 0.4 + 1/2

= -3/4 - 4/10 + 1/2

= -3/4 - 2/5 + 1/2

= -3/4 + 1/2 - 2/5

= -3/4 + 2/4 - 2/5

= -1/4 - 2/5

= -5/20 - 8/20

= -13/20 or -0.65

Hope it helps. Thanks!
