Question

Tính bằng cách thuận tiện: 6,25÷0,5+6,25:0,125

Answer 1

6,25:0,5+6,25:0,125

=6.25:\(\dfrac{1}{2}\)+6.25:\(\dfrac{1}{8}\)

=6.25.2+6.25.8

=6.25(2+8)

=6.25.10=62.5

Answer 2

Ta có: \(6.25:0.5+6.25:0.125\)

\(=\dfrac{25}{4}\cdot2+\dfrac{25}{4}\cdot8\)

\(=\dfrac{25}{4}\cdot\left(2+8\right)=\dfrac{25}{4}\cdot10=\dfrac{125}{2}\)
