Question

part a which multiplication fact can be used to help find 5,400 divided by 9? a ( 9 \times 5 = 45 ) b ( 3 \times 18 = 54 ) c ( 3 \times 3 = 9 ) d ( 9 \times 6 = 54 )

Explanation:

Step1: Analyze the division problem

The question asks for a multiplication fact to help find \(5400 \div 9\). Division is the inverse of multiplication, so we need a fact where \(9 \times \text{something} = 54\) (since \(5400 = 54 \times 100\), the core fact is \(54 \div 9\)).

Step2: Check each option

• Option A: \(9 \times 5 = 45\) (45 ≠ 54)
• Option B: \(3 \times 18 = 54\) (involves 3, not 9 directly)
• Option C: \(3 \times 3 = 9\) (unrelated to 54)
• Option D: \(9 \times 6 = 54\) (directly links 9 and 54, inverse is \(54 \div 9 = 6\), so \(5400 \div 9 = 600\))

Answer:

D. 9×6=54
