Ineed with this plz explaining to me

is simply explaining a few ways how to go about to converting a decimal format to a fraction format.  Let's do a couple examples on that.

say we have a number hmmmm 4.25, we can write that as 4 + 0.25, because 4 + 0.25 = 4.25.

now let's convert the 0.25 part to a fraction, we use as many zeros at the bottom as there are decimals and lose the dot atop, since that's a mouthful, let's proceed to do so then.

let's do another example say hmmmmm a longer decimal.... say 10.234578.

so that'll be 10 + 0.234578, because 10 + 0.234578 = 10.234578.

so let's make a fraction of 0.234578.

so, notice, we first look at how many decimals are there, and for the fraction, we use that many zeros, with the "1", namely a base of 10 with as many zeros, and we lose the dot on the numerator, and simplify from there.

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest
