How do you do, Increase £28 by 7%

The best thing is to find 1%. In order to do this, divide £28 by 100 & this gives you £0.28, then multiply this by 7 (as you're looking for 7%), and this gives you £1.96. You've then got to add these together, and that gives you £29.96 Hope this helps :)

I would find 5% so find ten percent which is £2.80 ( you just divide it by ten ) then half it £1.40 after that find 1% which is 28p (divide by 100) then add £1.40 and 28p which is £1.68 then add it to £28 which is ££29.68. That is what I would do but people like to do it other ways so Hope this helped you on how to answer these sort of questions
