Hello, Briana so when dividing fractions, its best to put them in decimal form so that you can divide or multiply better. Now having this in mind, 4.25 divided by 1.5 becomes the new equation and using simple math on a calculator, we can conclude that the answer to this question is 1.7 in decimal form or 1 and 7 over 10 in fraction form. Hope this helped, if you have any questions, please ask!

Variance and standard deviation - measures the variability of a data set about a fixed location, the mean. Variance is the square of the standard deviation.
Range - this is the difference between the largest and the smallest values in a data set.
