Please do a total of 18 portions is consumed per day calculate the number of portions that should come from each other of the food groups show calculations rounding of to the nearest integers
this way is good although i do it a diffrent way and try to reason it by doing the total frequency divided by the degrees in a circle for example in the 1st one he did 40 / 360 = 9, giving you the degrees in each individual slice so then as you go down the rows you times (9) with the number of slices needed (eg first row 6 x 9= 54 (degrees), second row 10 x 9=90 (degrees), thired row 4 x 9= 36 (degrees) ect, anyways just sharing the way i was taught if its confusing ignore me, not the best explination but its a good method
