Friday 3rd April

We know that % are something that many of you struggle with. Below is a code breaker which is a fun way to practise everything you have been taught. There are also some tips below to help you through it. Once you have an answer to each question, match it to the letter and then rearrange it to spell a phrase. Make sure to send us a picture of your work.

Percentages

ALL percentages (%) are out of 100. 

50% = a half

25% = one quarter

20% = one fifth

75% = three quarters

 

To find-
1% - divide by 100
10% - divide by 10
20% - divide by 5
25% - divide by 4
50% - divide by 2
75% - divide by 4 and multiply by 3
 
For numbers such as 72% of a number, I always say to find 1% and then multiply it up. 
 
A couple of examples of this:
72% of 900
1% of 900 = 9
so 72% of 900 = 9 x 72 = 648
 
63% of 450
1% of 450 = 4.5
so 63% of 450 = 4.5 x 63 = 283.5
