Question

solve. -7.1 × 3.7

Explanation:

Step1: Recall multiplication rules for signs

When multiplying a negative number and a positive number, the result is negative. So, \(-7.1\times3.7\) will be negative.

Step2: Multiply the absolute values

First, multiply \(7.1\) and \(3.7\). We can calculate \(71\times37 = 2627\). Since there are a total of \(1 + 1=2\) decimal places in \(7.1\) and \(3.7\), we place the decimal point in \(2627\) two places from the right, getting \(26.27\).

Step3: Apply the sign

From Step 1, we know the result should be negative. So, \(-7.1\times3.7=- 26.27\).

Answer:

\(-26.27\)
