Portfolio Multiplication Level 3

I am learning to solve multiplication problems at level 3
1.    When Jasmine makes lemonade she uses 6 lemons for every litre of water. How many lemons does she need for


i)     2 litres of water?   1ltr = 6 lemons so 2ltrs = 12


ii)    3 litres of water?   3ltr = 18 lemons    


iii)   10 litres of water?   10ltr = 60 lemons    


2.   Devinda is doing some baking. When he uses his mum's recipe he can make 8 muffins. When he doubles the recipe he gets 16 muffins. How many lots of the recipe does he need to make


i)     24 muffins?   24x8=?    20x8=160    8x4=32    160+32=192     


ii)    32 muffins?    32x8=?    10x8=80    3 groups of 80=220   8x2=16    220+16=236     


iii)   56 muffins?     8x56=?   8x10=80    5 groups of 80=160    160+160=320+80=400   8x6=48
400+48=448
