Answer: There are 60 blueberries .
Step-by-step explanation:
Given : The ratio of blueberries to strawberries is 2:7
i.e. [tex]\dfrac{\text{Quantity of blueberries}}{\text{Quantity of strawberries}}=\dfrac27[/tex]
If Quantity of strawberries = 20
Then,
[tex]\dfrac{x}{210}=\dfrac27\\\\\Rightarrow\ x=\dfrac27\times210\\\\\Rightarrow\ x= \dfrac{2}{7}\times210\\\\\Rightarrow\ x= 60[/tex]
Hence, There are 60 blueberries .
