Multiplication and Division

I am learning to work out multiplication and division problems in Level 3.

 1. When Jasmine makes lemonade she uses 6 lemons for every litre of water. How many lemon’s does she need for

i)     2 litres of water?    12 - 6 x 2 = 12, 6 doubled is 12.

ii)    3 litres of water?    18 - 6 x 3 = 18, 6 tripled is 18

iii)   10 litres of water?  60 - 6 x 10 = 60.

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

i)     24 muffins?     8 x 24 =?, 8 x 20 = 160, 8 x 4 = 32, 160 + 32 = 192.

ii)    32 muffins?     8 x 32 =?, 8 x 30 = ?, 8 x 10 = 80, 80 tripled is 220, 8 x 2 = 16, 16 + 220 = 236.

iii)   56 muffins?     8 x 56 =?, 8 x 50= ?, 8 x 10 = 80, 80 doubled five times = 400, 8 x 6 = 48, 400 + 48 = 448.
