Answer :

Put them all in the same form so they are easier to compare. I chose to put them all in decimal form.

square root of 58=7.616; 29/50=.58; -7.74; .5

So.... From least to greatest:

-7.74, .5, 29/50 (.58), square root of 58 (7.616)

Well an negative will always be smallest

-7.74

.5 is half and half is less than 29 over 50

.5
29/50

That only leave the square root of 58 the way you can figure this out is by taking the closest square root you know comes out even on both sides, 49 and 64, which are 7 and 8 respectively, which means it has to be larger than 29/50.

Square root of 58

Also this isn't History.
