Answer 2

1) To solve the expression 10 * 3 / 23 * 10, we follow the order of operations (also known as PEMDAS or BODMAS). In this case, we perform the multiplication and division from left to right.

10 * 3 = 30 30 / 23 ≈ 1.3043 1.3043 * 10 = 13.043

Therefore, the value of 10 * 3 / 23 * 10 is approximately 13.043.

2) For the expression 10 * 2 / 21 * 30:

10 * 2 = 20 20 / 21 ≈ 0.9524 0.9524 * 30 = 28.5714

So, the value of 10 * 2 / 21 * 30 is approximately 28.5714.

3) Let's evaluate the expression 4 * 5 / 15 * 16:

4 * 5 = 20 20 / 15 ≈ 1.3333 1.3333 * 16 ≈ 21.3333

Hence, the value of 4 * 5 / 15 * 16 is approximately 21.3333.

4) Lastly, we'll calculate the expression 8 * 9 / 27 * 16:

8 * 9 = 72 72 / 27 ≈ 2.6667 2.6667 * 16 ≈ 42.667

Therefore, the value of 8 * 9 / 27 * 16 is approximately 42.667.
