find 1.3 x 3.1
You asked:
Evaluate the expression: \(1.3 \cdot 3.1\)
MathBot Answer:
\[1.3 \cdot 3.1 = \frac{403}{100} = 4.03\]
\[\begin{aligned}1.3 \cdot 3.1& = \left(1 + \frac{3}{10}\right) \cdot \left(3 + \frac{1}{10}\right)\\& = \frac{13}{10} \cdot \left(3 + \frac{1}{10}\right)\\& = \frac{13}{10} \cdot \frac{31}{10}\\& = \frac{403}{100}\end{aligned}\]
