Explanation:

1. To solve this problem, convert all terms into improper fractions.

color(white)(XXXXx)2.25color(white)(XXXXXXXXXxx)11/3

color(white)(XXX)=225/100color(white)(XXXXXXXXX)=4/3

color(white)(XXX)=9/4

2. Multiply 9/4 by 4/3.

9/4xx4/3

3. Since 4 appears in the numerator and denominator twice, they cancel each other out. Similarly, since 9 in the numerator and 3 in the denominator can both be divided by a common factor of 3, their values are reduced.

=color(teal)cancelcolor(black)9^3/color(red)cancelcolor(black)4^1xxcolor(red)cancelcolor(black)4^1/color(teal)cancelcolor(black)3^1

4. Solve.

=color(green)(|bar(ul(color(white)(a/a)3color(white)(a/a)|)))
