Find the product of 20x9x5. Tell which property is used.
The answer is 900 because 20×9=180 and just multiply 180×5 and that equals 900.
Answer:
The property used is Commutative property.
Step-by-step explanation:
To find : The product of \(20\times 9\times 5\). Tell which property is used.
Solution :
Product of \(20\times 9\times 5\)
Applying Commutative property to make calculation easier,
i.e. \(a\times b=b\times a\)
Rearrange the terms,
\(20\times 9\times 5=(20\times 5)\times 9\)
Multiply first bracket,
\(20\times 9\times 5=100\times 9\)
Multiply,
\(20\times 9\times 5=900\)
Therefore, The property used is Commutative property.
