1. To add fractions you must have a
common denominator
2. Reduce fractions

COMMON DENOMINATOR
How do you get a common denominator?
8 can be the common denominator when the fractions are in fourths or eighths.
16 can be the common denominator for
all rulers marked in 16ths.
Use 32 as the common denominator when the ruler is marked in 32nds.
![Page 25: Read a tape measure](https://reader033.vdocuments.site/reader033/viewer/2022061616/56813b9a550346895da4cdf8/html5/thumbnails/25.jpg)
COMMON DENOMINATOR
Multiply top and bottom by the same value to change the denominator correctly.
