Problem K. 724. (March 2022)

K. 724. Julie cut a pizza into identical slices. Then she ate a few slices, but 3 slices remained. With a little calculation, she observed that she had eaten 3/4 of the whole pizza, plus 3/4 of a slice. How many slices were there?

Sorry, the solution is available only in Hungarian. Google translation

Megoldás. Az egész pizza 3/4 része plusz egy szelet 3/4 része plusz 3 szelet kiadja az egész pizzát. Tehát 3 egész 3/4 szelet a pizza negyedrésze, vagyis a pizza \(\displaystyle 4\cdot(3\frac34)=12+3=15\) szeletből állt.
