Answer:
[tex]2\frac{1}{4}[/tex] part of rice should be used.
Step-by-step explanation:
A recipe calls for 1 part beans to [tex]1\frac{1}{2}[/tex] part rice.
If [tex]1\frac{1}{2}[/tex] parts of beans used,
rice should be = [tex]1\frac{1}{2}[/tex] × [tex]1\frac{1}{2}[/tex]
= [tex]\frac{3}{2}[/tex] × [tex]\frac{3}{2}[/tex]
= [tex]\frac{9}{4}[/tex]
= [tex]2\frac{1}{4}[/tex] part or 2.25 parts rice
[tex]2\frac{1}{4}[/tex] part of rice should be used.
