In Basic Facts, the arithmetic operations such as addition, subtraction, multiplication, and division are performed mainly by using the one-digit numbers (1 to 9).
Addition fact is converse to the subtraction fact.
Multiplication fact is converse to the division fact.
5 + 7 = 12
8 - 5 = 3
3 × 4 = 12
18 ÷ 2 = 9
A. 72 ÷ 36 = 2
B. 72 ÷ 4 = 18
C. 72 ÷ 18 = 4
D. 72 ÷ 8 = 9
Correct Answer: D
Step 1: 8 ÷ 9 [Original expression.]
Step 2: 8, 9 are factors and 72 is the product. [8 ÷ 9 = 72.]
Step 3: Product becomes dividend, factors become divisor and quotient for division fact
Step 4: So, 72 ÷ 8 = 9 and 72 ÷ 9 = 8 are the division facts
Step 5: Here, 72 ÷ 8 = 9 is the division fact.
Q1: Which division fact can be used to find 8 x 9?
Q2: What is 5 + 7?
Q: What are basic facts?
A: Basic facts are simple arithmetic operations (addition, subtraction, multiplication, and division) involving single-digit numbers.
Q: Why are basic facts important?
A: They form the foundation for more complex math operations and problem-solving.
