Take the total amount of margarine used and divide it by the used per batch. 375/125 equals 3. This means James made 3 batches so we multiple the ammount of flapjacks per batch by the number of batches. 3*8 equals 24.
One recipe of flapjacks takes 125g of margarine and James is using 375. To find out how many recipes James is making divide the amount of margarine he is using (375g) by the amount of margarine needed in 1 recipe (125g).
375÷125=3
One recipe makes 8 flapjacks and since James is making 3 recipes you multiply 3 by 8 to get the number of flapjacks that James is making.
