The weight on the moon is approximately 16.5% of what you would weigh on Earth. Using this information, we can say that 16.5% of 42 lbs would equal how much the object would weigh on the moon.
I prefer to convert percentages the decimal way, so let's do it that way. 16.5% is 0.165 as a decimal, so now all we have to do is multiply 0.165 by 42 (since we are saying 16.5% of 42 lbs), and we get 6.93 lbs.
I can only use math to explain it. What is 100%? 100% = percent means per 100. so 120% = 120/100 = 1.2 120% of a whole number. For example 120% * 10 = = 12 is it greater than 10.
