\(\newcommand{\gt}{>}\)

Use mathematical notation to write “ $11.5$ is greater than $4.2\text{.}$ ”

Use mathematical notation to write “age is greater than $20\text{.}$ ”

Solution

$11.5\gt4.2$

We can just write the word age to represent age, and write $\text{age}\gt20\text{.}$ Or we could use an abbreviation like $a$ for age, and write $a\gt20\text{.}$ Or, it is common to use $x$ as a generic abbreviation, and we could write $x\gt20\text{.}$
