(12 × 105) ÷ (3 × 102)
To solve this expression, we can simplify the expression within the parentheses first:
(12 × 105) ÷ (3 × 102)
= (1260) ÷ (306)
Now, we can divide 1260 by 306:
= 4.11764705882
So, (12 × 105) ÷ (3 × 102) is approximately equal to 4.11764705882.
To solve this expression step-by-step, follow the order of operations (PEMDAS/BODMAS):
Step 1: Calculate the multiplication within parentheses.
12 × 105 = 1,260
Step 2: Calculate the multiplication outside the parentheses.
3 × 102 = 300
Step 3: Divide the result from step 1 by the result from step 2.
1,260 ÷ 300 = 4.2 (rounded to one decimal place)
So, (12 × 105) ÷ (3 × 102) = 4.2.
