Okay, so if the ratio is 2:1 (overall 3 sets), you would first divide 18 by 3, to get 6. You would then times 6 by the number on each side of the ratio. So you would get 12:6. This means there are 12 boys to every 6 girls, so the answer is 12 :)

We need to divide 18 by 3, as the total of ratios is 3 (ie, 2+1).
This gives 6. So there are 6*2=12 boys (and 6 girls).

be conscious that 2kg = 2000 g so the ratio of flour : butter : cheese available is 20:5:2 evaluating this to the mandatory 6:2:a million = 12:4:2, the cheese is the proscribing element (provided that with 2 units of cheese, you have the mandatory quantities of the different 2 factors, yet with occasion 5 units of butter, you like 2.5 units of cheese) to apply 2000 g of flour, you like 2000 / 3 = 667 g of butter and 2000 / 6 = 333 g of chese (and you do not have that lots of the two) so which you will use 1200 grams of flour : 4 hundred grams of butter : 2 hundred grams of cheese to furnish the mandatory 6:2:a million ratio it fairly is a finished of 1200 + 4 hundred + 2 hundred = 1800 grms of batter 1800 / 40 5 = 40 scones he could make 40 scones
