Multiplication and division (specifically) use remainders. Remainders are parts of a number that are left over. As an example, I have 4 cats and 10 cat treats. I can only give each cat 2 treats each, which means I will have 2 treats left over. The 2 left can't be divided by 4 as it is below 4, therefore the 2 is a 'remainder'. Remainders can be converted into fractions and decimals like so:
10 ÷ 4 = 2 r2 or 2.25 or 2^{1}⁄_{4}














Work out the calculations in brackets first

An eighth of a number is the same as saying divide it by 8


0.25 is the decimal equivalent of ^{1}⁄_{4}

72 x 10 = 720; half of 720 = 360, so 720 + 360 = 1,080


Just as 0.25 is ^{1}⁄_{4}
of 1, 25 is ^{1}⁄_{4}
of 100

e.g. ^{1}⁄_{12} of 66. One third is 22, half of 22 is 11, half of 11 is 5.5


Multiplying by 100 is much easier than multiplying by 99

You can use this strategy for other numbers over 100, for example to multiply a number by 107 multiply by 100 and also by 7 then add the 2 results together


To multiply a number by 10 move its decimal point 1 place to the right

To multiply a number by 100 move its decimal point 2 places to the right
