Given:
For every 3 seeds Lara planted, only 2 seeds grew.
Altogether, 12 seeds grew.
To find:
The number of total seeds planted by Lara.
Solution:
It is given that for every 3 seeds Lara planted, only 2 seeds grew. It means the ratio of total seeds planted to seeds grew is 3:2.
Altogether, 12 seeds grew.
Let x be the number of total seeds planted by Lara. Then,
[tex]x:12=3:2[/tex]
[tex]\dfrac{x}{12}=\dfrac{3}{2}[/tex]
[tex]x=\dfrac{3}{2}\times 12[/tex]
[tex]x=18[/tex]
Therefore, the total number of seeds planter by Lara is 18.
