2nd quarter POW #1

Quarter 2 POW #1 - this is a 7th grade problem!

Ms. Heron gave her son and grandchildren 12 acres of farmland. the farmland was rectangular in shape.

• She gave her son half of the 12 acres.
• She split the rest equally among the 3 grandchildren.

a. How many acres did Ms. Heron give to each grandchild? Show your work or explain how you know.

b. What fraction of the 12 acres did each grandchild receive? Show your work or explain how you know.

    a. The son got half of the 12 acres and 12/2=6. So the son got 6 acres. Ms. Heron has 3 grandchildren. 6 acres divided by 3 grandchildren is 2 acres each. So each grandchild gets 2 acres of land.

    b. Each grandchild has 2 acres and you want to know the fraction of acres each grandchild has out of the 12 acres. So the numerator is 2 and the denominator is 12. That number reduced is 1/6. Each grandchild gets 1/6 of the land.

  2. a. Ms. Heron's son got half of 12 acres which is 6. the grandchildren each got a third of the remaining 6 acres which would mean they each got 2 acres because 6/3=2.
    b. the fraction for how much land each of the grand children got would be 2/12 or 1/6 when simplified
