how we indicate 72 on number line​

Answer 1

ans see first you draw a number line .since you have to represent 72 you only draw the positive side but you can also add the negative side if you wish .then divide it into 10 divisions each like 0-10,10-20,20-30,30,40...70-80.then you add minor lines betwwen 70 to 80.then accordingly place 72.remember always put arrow at the last it is very important.please refre to the picture for convenience.
