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

The plant grew
`(7)/(6) \ in`, the first two weeks.

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
`(1)/(3) \ in`.

The second week it grew
`(5)/(6) \ in`.

The total growth was:

`(1)/(3) \ in+ (5)/(6) \ in=(6+15)/(18)=(21)/(18)=(7)/(6) \ in`

Therefore, the plant grew
`(7)/(6) \ in`, the first two weeks.
