Let's break down the expression step by step:
Therefore, the final result of the expression 0.4 (6.3 : 3.15 + 5/6 0.9) is 11.
Let's break down the expression step by step:
6.3 divided by 3.15 = 25/6 * 0.9 = 0.75Add the results of steps 1 and 2: 2 + 0.75 = 2.75Multiply 2.75 by 4 = 11Therefore, the final result of the expression 0.4 (6.3 : 3.15 + 5/6 0.9) is 11.
