Four hundred twenty is 3/5 of what number

420 divided by 3 equals 140.
140 times 5 equals 700.

you divide 420 by 3 since it is only 3/5ths. therefore you have to get it to 1/5th (aka 140) in order to get the total/complete number (aka 700).

hope this helps! have a good day/night

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
