Understand the problem: Understand the problem. We need to compare two numbers: 69.1 and 6.91 × 10^1. We need to determine which mathematical sign (>, <, or =) correctly represents the relationship between these two numbers.Convert to standard form: Convert the scientific notation to standard form. 6.91 × 10^1 means that we move the decimal point in 6.91 one place to the right, because the exponent on 10 is 1. 6.91 × 10^1 = 69.1Compare the numbers: Compare the two numbers. Now we have 69.1 ? 69.1. Since both numbers are identical, the correct sign is ＂=＂. 69.1 = 69.1

Understand the problem: Understand the problem. $\newline$ We need to compare two numbers: $69.1$ and $6.91 \times 10^1$ . We need to determine which mathematical sign (>, <, or $=$ ) correctly represents the relationship between these two numbers.
Convert to standard form: Convert the scientific notation to standard form. $\newline$ $6.91 \times 10^1$ means that we move the decimal point in $6.91$ one place to the right, because the exponent on $10$ is $1$ . $\newline$ $6.91 \times 10^1 = 69.1$
Compare the numbers: Compare the two numbers. $\newline$ Now we have $69.1 ? 69.1$ . Since both numbers are identical, the correct sign is ＂ $=$ ＂. $\newline$ $69.1 = 69.1$
