IT’S REALLY HARD TO KNOW HOW MUCH THAT IS!
SO BEFORE YOU TRY TO ADD THEM, MAKE IT SO BOTH FRACTIONS HAVE
AN EQUAL NUMBER PARTS.
![Page 16: Divide: . 1.) 2.75÷2.5= Round to the nearest thousandth: 2.) 456. 4584](https://reader030.vdocument.in/reader030/viewer/2022033020/56813815550346895d9fc99f/html5/thumbnails/16.jpg)
WHAT I MEAN BY EQUAL PARTS, IS MAKE IT SO BOTH FRACTIONS ARE CUT INTO THE SAME NUMBER OF PIECES.
3 PIECES 2 PIECES
