Question

Lara planted some seeds. For every 3 seeds Lara planted, only 2 seeds grew.

Answer 1

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,

$x:12=3:2$

$\dfrac{x}{12}=\dfrac{3}{2}$

$x=\dfrac{3}{2}\times 12$

$x=18$

Therefore, the total number of seeds planter by Lara is 18.
