    Evaluate the following without a calculator: make sure your answers make sense e.g. 4 ÷ 0.2 is really asking how many times 0.2 will “fit into” 4 – since 0.2 is only tiny, it will fit in more times than 2 does!

  1. \displaystyle{\frac{56}{0.8}}
  2. \displaystyle{\frac{36}{0.4}}
  3. \displaystyle{\frac{21}{0.7}}
  4. \displaystyle{\frac{10}{0.02}}
  5. \displaystyle{\frac{210}{0.003}}
  6. \displaystyle{\frac{81}{0.009}}

    7. Find the answer to these decimal divisions, without a calculator:

  7. \displaystyle{\frac{0.8}{0.2}}
  8. \displaystyle{\frac{1.2}{0.03}}
  9. \displaystyle{\frac{0.4}{0.001}}
  10. \displaystyle{\frac{0.004}{0.0001}}
  11. \displaystyle{\frac{0.12}{0.00003}}
  12. \displaystyle{\frac{0.006}{0.02}}
