Question

1. convert 1.4 to a simplified mixed number and a percent.

Explanation:

Step1: Convert to mixed number

The decimal 1.4 can be written as \(1 + 0.4\). The decimal \(0.4\) is equivalent to \(\frac{4}{10}\), which simplifies to \(\frac{2}{5}\) (dividing numerator and denominator by 2). So, \(1.4 = 1\frac{2}{5}\).

Step2: Convert to percent

To convert a decimal to a percent, multiply by 100. So, \(1.4\times100 = 140\%\).

Answer:

Mixed number: \(1\frac{2}{5}\), Percent: \(140\%\)
