Fact families are 3 numbers that are related, just as the people in a family are related. They make a set of related math facts.
Your speed is - mph. You travel for - hours. You travel- milies. Can you give me some fact families of that
The three fact families for the subtraction equation 1803 - 925 are: 1803 - 925 = 878 925 + 878 = 1803 878 + 925 = 1803 These equations demonstrate the relationship between addition and subtraction using the same numbers.
878 is the answer to the problem and the full answer would be 878,925+878+1803I remember when i was in 5th grade ^-^ (Math can be tough it sure is for me)
all the fact families of 80 is 23+4
878 = DCCCLXXVIII in Roman numerals
It is (677 + 878)/2 = 777.5
878 - 766 = 112 as there are 2 numbers divide by 2 112 / 2 = 56 766 + 56 = 822 = 878 + 56

The average of 878 and 722 is 800.
how many other fact families with dividends under 100 contain exactly three different digits? Name one multiplication fact in each of these families
because fact families are like this 2+2=4,4-2=2 and adding
(766+878)/2 = 1644/2 = 822822. Add the two numbers together and divide by 2.The average is: (766+878)/2 = 822
