Answer 3

Task 1: Weight of Two Watermelons

The problem states that the father bought two watermelons, with one weighing 6 kg and the other being half the weight of the first one. We need to find the total weight of the two watermelons.

To solve this problem, we can add the weight of the first watermelon (6 kg) to half of its weight.

The weight of the second watermelon is half of the weight of the first watermelon, which is 6 kg / 2 = 3 kg.

Therefore, the total weight of the two watermelons is 6 kg + 3 kg = 9 kg.

Answer: The two watermelons weigh 9 kg.

Task 2: Stickers in an Album

The problem states that Olya has 12 stickers and Dasha has 18 stickers. They want to distribute all their stickers equally on three pages in an album. We need to find the number of stickers that will be on each page.

To solve this problem, we can divide the total number of stickers by the number of pages in the album, which is 3.

The total number of stickers is 12 + 18 = 30 stickers.

Therefore, the number of stickers on each page is 30 stickers / 3 pages = 10 stickers.

Answer: There will be 10 stickers on each page.

Task 3: Bags of Flour

The problem states that there is 21 kg of flour, and we need to distribute it equally into 7 bags. We need to find the number of bags required to distribute 12 kg of flour.

To solve this problem, we can divide the total weight of flour by the number of bags.

The total weight of flour is 21 kg.

Therefore, the weight of flour in each bag is 21 kg / 7 bags = 3 kg.

To find the number of bags required to distribute 12 kg of flour, we divide the desired weight by the weight of flour in each bag.

The desired weight is 12 kg.

Therefore, the number of bags required is 12 kg / 3 kg = 4 bags.

Answer: Four bags are required to distribute 12 kg of flour.
