Question

Simplify the expression 1 + 0.25 (8 + 12) - 0.3 × 2

Answer 1

Question: Simplify the expression 1 + 0.25 (8 + 12) - 0.3 × 2​

Solution:

Distributing 0.25 in the sum we obtain:

$1\text{ + (0.25x 8 + 0.25 x12) - 0.6}$

Performing each of the operations we obtain:

$1\text{ + (2 + 3) - 0.6}=\text{ 1 + 5 -0.5 = 5.5}$

So the correct answer is

$1+0.25(8+12)-0.3\times2​\text{= 5.5}$
