Question

reflect
hazel is trying to solve this equation.
9 × 8,000 = ?
she says the answer is 7,200.
is hazel correct or incorrect? explain why or why not.

Explanation:

Step1: Calculate 9×8,000

First, we know that \( 9\times8 = 72 \). Then, since 8,000 has three zeros (representing \( 10^3 \)), we multiply 72 by \( 10^3 \), which gives \( 72\times1000 = 72,000 \).

Step2: Compare with Hazel's answer

Hazel's answer is 7,200. But we calculated the correct result as 72,000. Since \( 72,000
eq7,200 \), Hazel made a mistake in the number of zeros she accounted for when multiplying.

Answer:

Hazel is incorrect. The correct calculation is \( 9\times8,000 = 72,000 \), while Hazel's answer is 7,200, which is wrong because she miscalculated the number of zeros in the product.
