Question

Q1.

Barney is going to bake a cake.
He uses 250 grams of flour for the cake.
He adds 14 grams of baking powder for each 150 grams of flour.
(a) How much baking powder does Barney add to 250 grams of flour?
Give your answer correct to the nearest gram.

Answer 1

Explanation:

You cross multiply. So it's 14 times 250 divided by 115.

That's how much you would add to the 250 mixture.

14 times 250 is 3500, Divided by 150= 23 and a third.

It does say round to the nearest gram.

So we had to add about 23 g to 250 g of flour.
