Put this in descending order 3/8,-5/16,-0.65,2/4

to solve this, you have to put all of the integers with a common denominator - so first put them all in a fraction

so all the fractions are:

3/8, -5/16, -3/20, 2/4

now put them all in a common denominator form over 320

120/320, -100/320, -48/320, 160/320

so negative numbers are the least so we'll leave them for the end (descending)

the order will now be:

160/320, 120/320, -48/320, -100/320,

now put these in the form of the real integers:

2/4, 3/8, -3/20, -15/16

-5/16, -0.65, 3/8, 0.5

To do this i just put the fractions in decimal form

3/8 =0.375

-5/16=-0.3125

2/4+0.5

113.1
