Question
Mary baked a cake with 140g of flour.She also baked brownies with 45% more flour than she used in her cake.How much flour did she use to make brownies?
Solution
To find out how much flour Mary used for the brownies, we need to calculate 45% of the amount of flour she used for the cake, which is 140g.
Step 1: Find 45% of 140g To do this, we multiply 140 by 45/100 (which is the decimal equivalent of 45%). 140 * 45/100 = 63g
This means that Mary used 63g more flour for the brownies than she did for the cake.
Step 2: Add this to the original amount of flour used for the cake To find the total amount of flour used for the brownies, we add this 63g to the original 140g. 140g + 63g = 203g
So, Mary used 203g of flour to make the brownies.
