Students attached both ends of a long wire to the poles of a battery and wrapped the wire around a spoon. In this arrangement, the spoon is able to pick up five paper clips.
The students wrap more wire around the spoon and want to determine if the strength of the magnetic force has increased. Which of the following
observations would indicate that wrapping more wire has increased the strength of the electromagnet?

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
