Finding exact measurements

Transcript

Finding exact measurementsWe find the exact measurements using precise number line Screw is between 2 cm and 3 cm. But this is not accurate If we divide 2 and 3 in half = we get screw more than 2 ½ cm , but this is still not accurate If we divide 2 and 3 in ten parts, we get an accurate reading of 𝟐 𝟕/𝟏𝟎 cm Let’s try this one Screw is greater than 3 cm. But this is not accurate If we divide 1, 2 and 3 in half = we get screw less than 3 ½ cm , but this is still not accurate If we divide 3 and 4 in ten parts, we get an accurate reading of 𝟑 𝟐/𝟏𝟎 cm
