Write afact family with the sum of 17. Explain how you picked the addends.
Fact families are trios of numbers that are used for addition and subtraction.
9+8=17
8+9=17
17-9=8
17-8=9
You can do this for just about any set of numbers. Other addends for 17 would be 10 and 7, 15 and 2, etc.
=)
How do you exlain how you picked the addends you used
i like number 9
i was stuck on this for half an hour lol, but now iām done!
A fact family is a group of math facts that are related to each other. To create a fact family with a sum of 17, we need to come up with three numbers that can be added together to give us that sum.
Let's start by picking one number. We'll choose 9 as our first addend.
Now we can think about the second addend. Since we want the sum to be 17, we just need to subtract 9 from 17 to find the missing number. So, 17 - 9 = 8. Therefore, our second addend is 8.
Finally, we can find the third addend by subtracting the sum of the first two addends from the desired sum. In this case, 9 + 8 = 17, so we can conclude that our third addend is 17 - (9 + 8) = 17 - 17 = 0.
So, the fact family with a sum of 17 would be: 9 + 8 = 17 and 8 + 9 = 17, showing the relationship between these numbers.
