Question

Which is the closest approximation to the product 0.3333 x 0.25 x 0.499 x 0.125 x 24 ? How to solve it faster

Answer 1

$\frac{3333}{10000} \times \frac{25}{100} \times \frac{499}{1000} \times \frac{125}{100} \times 24 \\ = \frac{3333 \times 25 \times 499 \times 125}{100000000000} \times 24$
That would give u
1.24737525 or 1.25
