You can either convert the decimal to a fraction and then subtract (3/4 - 0.5 = 3/4 - 2/4 = 1/4), OR you can convert the fraction to a decimal and then subtract (3/4 - 0.5 = 0.75 - 0.5 = 0.25).
Well, honey, if you want to subtract 0.5 from 0.05, you're gonna end up with a negative number. Technically, you can do the math by borrowing and carrying over decimals, but let's be real - that's just a whole lot of unnecessary work for a result that doesn't make much sense. Just keep it simple and know that 0.05 minus 0.5 is -0.45.
