List the fractions and decimals in order from least to greatest...
16. -3/8 , 5/16, -0.65, and 2/4?
Please explain to me. I'm very confused!

In order to list them from least to greatest is by finding the smallest number first. Negative numbers are always less than positive, so -3/8 and -0.65 have to be ordered first. -3/8 or -0.38 is greater than -0.65, so -0.65 would be first. Then the next negative which is -0.65 comes next. the last two fractions are 2/4 or 1/2 or 0.5 and 5/16 or 0.31. 0.5 is greater than 0.31, so the order is -0.65, -3/8, 5/16, and 2/4. Hope this helps!
