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.
