let's see if we can write 1.50 one as a percentage now we really just want to write this quantity as something over 100 so what we can do is we can say that this is the same thing as 1 point 5 0 1 over 1 we haven't change this value and let's multiply it times 100 over 100 when we do this product and I haven't changed the value this is just multiplying something times 1 but when we do it we're going to change the way that we're representing it the denominator now is going to be 1 times 100 so that's pretty straightforward that's just going to be 100 and then the numerator we're going to want to multiply 1.50 1 times 100 and so this is going if we multiply this times 10 we would move the decimal 1 over we want to multiply it by 100 so we want to multiply it by 10 again so we're going to move the decimal over to the right twice we're multiplying it by 10 twice or you're multiplying it by 100 this is multiplying by 10 this is multiplying by 100 so this is where the decimal is going to sit now so we're going to get 150 point 1 and so we've rewritten 1 point 5 0 1 is 150 point 1 over 100 or 150 point 1 per hundred let me write that 150 point 1 per per hundred which is the same thing as 150 point 1 percent which is the same thing as 150 point 1 150 point 1 percent and we're done and essentially all you're doing if you really want to simplify the process we're multiplying this by 100 to get 150 point one and then we're saying that is the percentage so you want to make sure that you write the percent there or the percent symbol
