Well, darling, the fact family of 8, 5, and 40 consists of the numbers 8, 5, and their products and division results. So, in this case, the fact family would be 8 x 5 = 40, 5 x 8 = 40, 40 ÷ 8 = 5, and 40 ÷ 5 = 8. It's as simple as that, sugar.
1 x 35, 5 x 7, 7 x 5, 35 x 1 = 35
3+5=8
Well, honey, the fact family for 5, 10, and 50 is pretty straightforward. You take the numbers given and see how they relate through addition and subtraction. In this case, you've got 5 + 10 = 15, 10 - 5 = 5, 5 x 10 = 50, and 50 ÷ 10 = 5. Voilà, you've got yourself a fact family!
1x5=5, 5x1=5,5 divided by 5=1, and 5 divided by 5=1.
