22 + 49=
To make one addend a ten, we need to subtract 1 from that addend and add it to the other addend.
Let's apply this to the given addition sentence: 22 + 49 = ?
We will make the addend 49 a ten. We subtract 1 from 49, which gives us 48. Then, we add 1 to the other addend, 22, resulting in 23.
Now we can complete the new addition sentence:
23 + 48 = ?
Simply add the new addends to find the sum:
23 + 48 = 71
Therefore, the new addition sentence is:
22 + 49 = 23 + 48 = 71
