Question

Katya measured the growth of a plant seedling. The seedling grew 1/3 inch by the end of the first week and another 5 / 6 inch by the end of the second week. About how much did the seedling grow in the first 2 weeks? Explain how you made your estimate.

Answer 1

The seedling grew 1 1/6 inches or approximately 1.16 inches. 1/3 is equal to 2/6, 2/6 + 5/6 = 7/6
7/6 = 1 1/6

Answer 2

Answer:

The plant grew $\frac{7}{6} \ in$, the first two weeks.

Step-by-step explanation:

To find how much grew the plant in the first 2 weeks, we just have to sum both growth numbers.

In the first week it grew $\frac{1}{3} \ in$.

The second week it grew  $\frac{5}{6} \ in$.

The total growth was:

$\frac{1}{3} \ in+ \frac{5}{6} \ in=\frac{6+15}{18}=\frac{21}{18}=\frac{7}{6} \ in$

Therefore, the plant grew $\frac{7}{6} \ in$, the first two weeks.
