Final answer:
All four calculations a) 4.5÷0.09, b) 45÷0.9, c) 450÷9, d) 4500÷90 have the same result, which is the common value of 50.
Step-by-step explanation:
The student has asked what the common value is for the following calculations: a) 4.5÷0.09, b) 45÷0.9, c) 450÷9, d) 4500÷90. To solve these, we'll perform each division separately and determine if there's a common result.
- For (a) 4.5÷0.09, we divide 4.5 by 0.09 which gives us 50.
- For (b) 45÷0.9, dividing 45 by 0.9 also gives us 50.
- For (c) 450÷9, 450 divided by 9 equals 50.
- For (d) 4500÷90, similarly, dividing 4500 by 90 results in 50.
The common value for each expression is 50.
