Length of straw1 is : 2 |
Length of straw2 is : neither 2 nor 3. So to measure the length of straw2 lets divide the length between 2 and 3 into 10 equal portions. and each one portion out of ten is 1/10 or tenth. Now you can see that straw2 extends upto 5 small portions after 2. therefore Length of straw2 is : 2.5 |
Length of straw3 is : more than 2.7 but less than
2.8 So to measure the length of straw3 lets divide length between 2.7 to 2.8 into 10 equal portion. and each small one portion is 1/100 or hundredth. Now you can see that straw3 extends upto 3 small portions after 2.7. therefore Length of straw3 is : 2.73 |
