Question

Now suppose you have 300 eggs, but only 70% of those eggs progress to become a caterpillar, and only 80% of the caterpillar progress to become an adult butterfly. how many butterflies do you have?

Answer 1

70% = 70/100 = 0,7
80% = 80/100 = 0,8

300 * 0,7 = 210  [caterpillars]
210 * 0.8 = 168  [butterflies ]

Answer 2

Answer:

You have 168 butterflies

Step-by-step explanation:

Total no. of eggs = 300

Only 70% of those eggs progress to become a caterpillar

No. of caterpillar = $70\% \times 300$

No. of caterpillar = $\frac{70}{100} \times 300$

No. of caterpillar = $210$

Only 80% of the caterpillar progress to become an adult butterfly

No. of butterfly = $80\% \times 210$

No. of butterfly = $\frac{80}{100} \times 210$

No. of butterfly = $168$

Hence you have 168 butterflies
