Vilket tal är en tiondel större än 0,7 ? Vilket tal är en tiondel mindre än 0,4 ?

A ladder has 50 rungs. The bottom rung is 1 m long. Each rung is \( 12,5 \mathrm{~mm} \) shorter than the rung beneath it. Determine the total length of wood required to make 50 rungs.

If I write the three measurements in descending order, which one will be in the middle? Select one: \( \begin{array}{l}54,9 \mathrm{~km} \\ 45,09 \mathrm{~km} \\ \text { - } 450,9 \mathrm{~km}\end{array} \)

e) \( 1 \frac{1}{3}+2 \frac{1}{4}-3 \frac{5}{12} \)
