Divide starting amount by bottom x by the top.

eg. 3/4 of £100 = 100 /4 x 3 = £75]]> 2018-01-22 10:49:39 UTC https://padlet.com/adrian_dalzell/t6mtanughcx1/wish/223263449 Percentages adrian_dalzell https://padlet.com/adrian_dalzell/t6mtanughcx1/wish/223325185 (%/100) x £

e.g. A pair of shoes cost £50,They are reduced by 25%. What is their new price?

(25/100) x £50 = £12.50.
£50 - £12.5 = £37.50]]> 2018-01-22 14:00:15 UTC https://padlet.com/adrian_dalzell/t6mtanughcx1/wish/223325185 Reverse Calculations adrian_dalzell https://padlet.com/adrian_dalzell/t6mtanughcx1/wish/223326106 a+b+=c

(% / 100) x £ 

eg. 12.5% discount of £200 =

(12.5 / 100) x £200 = £25

Checking Percentage questions

Show only decimal equivalent i.e. .125 x £200 = £25
£25  / £200 = .125

Remember percentage increase

increase of 12.5% would = 1.125

Use squares on screen/paper

Each Cm square will be equivalent to original size measurement. 

Divide OS measurement by number of squares to find out what 1cm equals

Divide original size scale by how many 1/5s to find out what each .2 of a cm is = to.

i.e. 2, 3, 4, 5, 6 = 20
20 / 5 = 4.

Q. Why did you use the mean?

Beacause it uses all the values. 

If zeros present, include these as a value to divide by.

Q. What does the mean/average show?

Possible answers:

Improving, Decreasing, from previous results/year/week etc.]]> 2018-01-24 09:50:46 UTC https://padlet.com/adrian_dalzell/t6mtanughcx1/wish/224136761 Range adrian_dalzell https://padlet.com/adrian_dalzell/t6mtanughcx1/wish/224137015 Biggest value - Smallest
