You plant 20 marigold seeds and 12 of them grow into flowers that bloom. If you plant 10 more merigolds, predict how many would bloom

Use the ratio 20/12.

$$20 \over 12$$$$=$$

$$30 \over x$$

Cross multiply, and you'll get $$12x = 20*30$$

$$12x = 600$$

$$x= 600/12 = 20$$

Thus, 20 seeds would bloom.

12 / 20 =60% of the marigolds bloomed.

60% =0.6 x 10 =6 more marigolds expected to bloom.

12 + 6 = 18 expected number of marigolds out of 30 planted.
