Question

Write the multiplication fact family using the set of numbers 2 , 5 , and 10.

  1. 2 × 5 = 10 , 5 × 2 = 10
  2. 10 ÷ 2 = 5 , 10 ÷ 5 = 2
  3. 10 × 2 = 20 , 2 × 10 = 20
  4. 10 – 2 =8 , 10 – 5 = 5

Hint:

Family is a group of Mathematical equations or facts which are created when we use same set of number. The result which we get by using the numbers must be same. We use the given numbers to find the set of numbers which generate same results.

The correct answer is: 2 × 5 = 10 , 5 × 2 = 10


    Family is a group of Mathematical equations or facts which are created when we use same set of number. The result which we get by using the numbers must be same.
    Step1: Calculating the set of values from the family members.
    Here in this question we are given set of number as 2 comma 5 and 10.
    We know that we can get 10 by multiplying 2 by 5 and we can also get 10 by multiplying 5 by 2. So, we get the set of fact family as:
    Step2: Finding the relevant Pairs from the fact family
    2 cross times 5 space equals 10 and also,
    5 cross times 2 equals 10
    So, the result we get from using the fact family are 5 cross times 2 equals 10 and 2 cross times 5 space equals 10
