Question

(2ч3мин×9-6ч2мин×3)×9+9ч12мин:8

Answer 1

(123×9-362×3)×9+552÷8=258

Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Convert the given time values to minutes. 2 hours 3 minutes = 2 * 60 + 3 = 123 minutes 6 hours 2 minutes = 6 * 60 + 2 = 362 minutes 9 hours 12 minutes = 9 * 60 + 12 = 552 minutes

Step 2: Simplify the expression using the order of operations (PEMDAS/BODMAS).

(2h 3m × 9 - 6h 2m × 3) × 9 + 9h 12m ÷ 8

= (123 × 9 - 362 × 3) × 9 + 552 ÷ 8

= (1107 - 1086) × 9 + 69

= 21 × 9 + 69

Step 3: Perform the multiplication and addition.

= 189 + 69

= 258

Therefore, the value of the given expression is 258.
