Question

Solve: 3/8[-8 + 16 - (-2 and 1/2)]

Answer 1

To solve the expression, simplify inside the brackets to get 21/2 and then multiply by 3/8 to get the solution which is 63/16.

Step-by-step explanation:

To solve the given expression 3/8[-8 + 16 - (-2 and 1/2)], we first need to simplify the expression inside the brackets. Let's convert the mixed number -2 and 1/2 into an improper fraction. Since -2 and 1/2 is equal to -2 - 1/2, this becomes -5/2 when converted to an improper fraction.

Now, we simplify the expression within the brackets as follows:

Next, we multiply 3/8 by 21/2:

Therefore, the solution is 63 / 16.

Answer 2

63/16 or 3 15/16.

Step-by-step explanation:

Solve: 3/8[-8 + 16 - (-2 and 1/2)] Using order of operations (PEMDAS):

=3/8[-8 + 16 - (-2.5)]

= 3/8( 8 + 2.5)

= 3/8(10.5)

= 31.5/8

= 63/16.
