When you divide 4 by 15 the closest number you will get to 15 that is is multiple of 4 is 12 and 15 - 12 is 3 so tell that 3 on the bottom would be your whole number and the 3 on top would be the numerator and the 4 would be the denominator
First divide 15 on 4 to get 3.75. convert 3.75 to a fraction. 3 will stay as three, and 0.75 will be converted to 3/4. the answer to your question is 3 and 3/4. I hope this was correct. if it was then please mark as brainliest.
