Mason wants to know how many items of fruit he bought. Answer the questions to help him. He counts in 100s to find how many cherries he has. Then, he counts in 10s to add the watermelons. What three numbers should he say after 310? 100, 200, 300, 310, what, what, what.

In this question, we’re being asked to count in 100s and 10s to help Mason find out how many pieces of fruit he has. The cherries come in boxes of 100. So he started to count his cherries in 100s. 100, 200, 300. Mason also bought some watermelons, which come in boxes of 10. So we need to start counting at 300 and keep on counting in 10s. 300, 310, 320, 330, 340. Now, we know that Mason had 340 pieces of fruit, the three numbers that he should say after 310 are 320, 330, and 340.

First, Mason counted his cherries in 100s: 100, 200, 300. He counted his watermelons in 10s: 310, 320, 330, 340. So the missing numbers are 320, 330, and 340.

He also bought some oranges. Count on to figure out how many pieces of fruit he has in total.

We know that Mason bought three boxes of cherries. Each box contained 100 cherries. And he bought four boxes of melons, and the melons came in boxes of 10. So we can start counting at 100. 100, 200, 300. We need to keep on counting in 10s now because the watermelons came in boxes of 10. 310, 320, 330, 340. And we can count the oranges in ones. The oranges are single pieces of fruit. They haven’t been grouped together in 10s or 100s. We count these as ones. 341, 342, 343, 344, 345, 346, 347. We counted in 100s, 10s, and ones. The total number of pieces of fruit that Mason bought is 347.
