Question

1. compare the expressions below using <, >, = to create true comparisons.

9.3×1.1 9.3
6×0.4 0.4
0.7×0.2 0.8

Explanation:

Step1: Compare \(9.3 \times 1.1\) and \(9.3\)

Since \(1.1>1\), multiplying \(9.3\) by a number greater than \(1\) will make the result larger than \(9.3\). So \(9.3 \times 1.1>9.3\).

Step2: Compare \(6 \times 0.4\) and \(0.4\)

Since \(6 > 1\), multiplying \(0.4\) by a number greater than \(1\) will make the result larger than \(0.4\). So \(6\times0.4 > 0.4\).

Step3: Compare \(0.7\times0.2\) and \(0.8\)

First, calculate \(0.7\times0.2 = 0.14\). Since \(0.14<0.8\), so \(0.7\times0.2<0.8\).

Answer:

\(9.3 \times 1.1>9.3\)；\(6\times0.4 > 0.4\)；\(0.7\times0.2<0.8\)
