Hernan cuts a board that is 7/10 of a meter long After the cut the board is 3/10 of a meter long how long is the piece that he c
Darina [25.2K]

Given that original lenght of the board before cut = \frac{7}{10}meter

Lenght of the board that is left after cutting from the original piece by Hernan = \frac{3}{10}meter


Now we have to find the lenght of the piece which is cut.

To find that we just need to subtract smaller piece from larger piece


Required Length = \frac{7}{10}-\frac{3}{10}meter

Required Length = \frac{7-3}{10}meter

Required Length= \frac{4}{10}meter

reduce the fraction

Required Length = \frac{2}{5}meter


Hence final answer is \frac{2}{5} meter.
