Increase £190 by 25%

There are two ways to work out the answer to this question. The first way involves first working out 25% of £190 and then adding this to your original £190. To calculate 25% of £190 we multiply 190 by 0.25 as 25%=25/100=0.25. This gives us £47.50. Then we add this value to our original £190 to get a final answer of £237.50. The other way to solve this question is slightly quicker. Rather than using two steps we can multiply our original £190 by 1.25. This again gives us £237.50. This is because by multiplying by 1.25 we are technically including the original £190 in our calculation. We can see this is correct by focusing a bit more on the first calculation. In this we did 0.25190+1190. By factorsing we get 190*(0.25+1)=190*(1.25) which is exactly what we did in this second method.
