2.51 x 19.5
You asked:
Evaluate the expression: \(2.51 \cdot 19.5\)
MathBot Answer:
\[2.51 \cdot 19.5 = \frac{9789}{200} = 48.945\]
\[\begin{aligned}2.51 \cdot 19.5& = \left(2 + \frac{51}{100}\right) \cdot \left(19 + \frac{5}{10}\right)\\& = \frac{251}{100} \cdot \left(19 + \frac{5}{10}\right)\\& = \frac{251}{100} \cdot \left(19 + \frac{1}{2}\right)\\& = \frac{251}{100} \cdot \frac{39}{2}\\& = \frac{9789}{200}\end{aligned}\]
