Answer 3

Answer:

а) Let's solve the problem step by step. We know that the weight of the apple is 123g and the weight of the pear is 216g. The weight of the orange is the same as the combined weight of the apple and the pear.

To find the weight of the orange, we need to add the weights of the apple and the pear:

123g (apple) + 216g (pear) = 339g

Therefore, the weight of the orange is 339g.

Now, to find the total weight of the apple, pear, and orange combined, we simply need to add their weights:

123g (apple) + 216g (pear) + 339g (orange) = 678g

Therefore, the total weight of the apple, pear, and orange combined is 678g.

б) We are given that the weight of the textbook is 270g, and Misha put two textbooks in his bag. The weight of the empty bag is 350g.

To find the weight of the bag with the textbooks, we need to add the weight of the textbooks to the weight of the empty bag:

270g (textbook) + 270g (textbook) + 350g (empty bag) = 890g

Therefore, the weight of the bag with the two textbooks is 890g.
