Suppose that a positively charged piece of tape has a charge of 2.00 x 10^-2C and an excess of 1.25 X 10^17 protons. calculate the elementary charge

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

the answer should be in the picture.
