Answer:

(OE) 400

Step-by-step explanation

you can translate 25% to 1/4.

think of it as a pie that you have to share between yourself and 3 of your friends into 4 equal slices; the first slice signifies 100 and you have to cut 3 other slices. this means you've got to multiply 100 by 4 (because every slice has to be equal and therefore all signify 100 and you've cut 4 slices) to get to the answer; 400
