Question

which expression is equivalent to 25 a. (8×4-2) ×3 +8 ÷ 2 b.8 x (4-2) ×3 + 8 ÷ 2 c. 8×4-(2×3+8)÷2 d.8×4- 2 ×3 + 8 ÷2

Answer 1

The answer is C.

Proof:
8×4-(2×3+8)÷2
=32-(6+8)÷2
=32-14÷2
=32-7
=25

Answer 2

Answer:

c. 8×4-(2×3+8)÷2

Step-by-step explanation:

Using the rules of BODMAS,

B stands for  bracket

O stands for Order

D stands  for Division

M stands for Multiplication

A stands for Addition

S stands for Subtraction

8×4-(2×3+8)÷2

Now using this rule we will first of all open the bracket, In the bracket we multiply then add

8 × 4 - (6 +8) ÷ 2

8 × 4 - 14 ÷ 2

Still applying the rule, we divide 14 by 2 to give us 7

8 × 4  - 7

Then, still applying the rule, we multiply 8 by 4 which will give us 32

32 - 7

Then we finally subtract 7 from 32 to give us 25

32 - 7 = 25

So the expression;  8×4-(2×3+8)÷2    is equivalent to 25
