Check all that apply to determine the following conversion. 4 km = ? mm
•Move the decimal place over 6 until to the right
• Move the decimal place over 6 units to the left
•Divide 4 km by 1’000’000 to calculate mm
• Multiply 4km by 1’000’000 to calculate mm
• Add 1’000’000 to calculate mm
• Move the decimal place 6 units left, then 2 units to the right

4 km -> 400,000 mm

put a decimal point at the end of 4 and move it to the left 6 times because we know that 1 km is equal to 100,000 and it has zeros.

hence, it is proven that 4 km is equal to 4000,000.

answer: procent 54 wynosi 33,33%

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.
