Answer: \(\dfrac{7}{10}\) pounds.
Step-by-step explanation:
Given : Emily is buying \(\dfrac{2}{5}\) of a pound of beans for dinner.
Ricki is buying \(1\dfrac{3}{4}\) of the amount of beans that Emily is buying.
Here, \(1\dfrac{3}{4}\) can be written as \(\dfrac{4+3}{4}=\dfrac{7}{4}\)
Then, the amount of beans bought by Ricky is given by :_
\(\dfrac{7}{4}\times\dfrac{2}{5}\\\\=\dfrac{7}{10}\)
Hence, Rick is buying \(\dfrac{7}{10}\) pounds.
