You simply use this operation:
- total students are 305, we need to find how many of thm play instrumenst if 40% does.
40% can be rewrited as 0,4 in decimal.
than we simply utilise a basic percentage operation which allows us to find A PART of somethin=>
305×0,4= students who instruments.
To draw a locus point you have to draw the half way line through the two points. You can do this by drawing the line bisector through AB points. Just open your compass to ¾ of the distance AB and then draw two arcs from both sides of your line. Once this is done draw the line passing through the two intersection points.
Hope this helps :)
