how is it making 10
explain the math plz
To make adding these numbers easier, you can break them down into groups of 10.
Starting with the initial count of 17 puppies, Janet can group this as 10 + 7.
Then when she counts 12 more puppies, she can group this as 10 + 2.
Now, you can add the groups together:
10 (from the initial count) + 10 (from the additional count) = 20
7 (from the initial count) + 2 (from the additional count) = 9
Now, you add the two totals together: 20 + 9 = 29.
So, Janet counted a total of 29 puppies at the park.
u did not make 10 tho 7 + 2 is 9 and 10 + 10 is 20 how did u make 10
I apologize for the oversight in my explanation. Let's break it down differently to show making 10s to simplify the addition:
Janet counts 17 puppies at the park. To make 10, you can break down 17 as 10 + 7.
Then when she counts 12 more puppies, break down 12 as 10 + 2.
Now for the addition:
10 (from the initial count) + 10 (from the additional count) = 20
7 (from the initial count) + 2 (from the additional count) = 9
Now, add the 10s together: 20
Then add the 1s together: 9
Finally, add the sums together: 20 + 9 = 29
So, Janet counted a total of 29 puppies at the park.
