Answer 1

10\24=2,4
50•5,5=275
16+15\2=15,5
904+36\2=922

Answer 2

Calculation A: (76-66)/3×8

To solve this expression, we follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the calculation step by step:

1. Subtract 66 from 76: 76 - 66 = 10. 2. Divide the result by 3: 10 / 3 = 3.3333 (rounded to four decimal places). 3. Multiply the quotient by 8: 3.3333 * 8 = 26.6664 (rounded to four decimal places).

Therefore, the value of (76-66)/3×8 is approximately 26.6664.

Calculation B: (14+36×11/2)

Again, we'll use the order of operations to solve this expression:

1. Multiply 36 by 11: 36 * 11 = 396. 2. Divide the result by 2: 396 / 2 = 198. 3. Add 14 to the quotient: 198 + 14 = 212.

Therefore, the value of (14+36×11/2) is 212.

Calculation C: (16+180:12)/2

Let's solve this expression step by step:

1. Divide 180 by 12: 180 / 12 = 15. 2. Add 16 to the quotient: 15 + 16 = 31. 3. Divide the sum by 2: 31 / 2 = 15.5.

Therefore, the value of (16+180:12)/2 is 15.5.

Calculation D: 904+(12×3)/2

Lastly, we'll calculate this expression:

1. Multiply 12 by 3: 12 * 3 = 36. 2. Divide the product by 2: 36 / 2 = 18. 3. Add 904 to the quotient: 904 + 18 = 922.

Therefore, the value of 904+(12×3)/2 is 922.

I hope this helps! Let me know if you have any further questions.
