After you read this answer, you will! :DYou want to solve for d, so you want to divide both sides by 1.5 because it'll cancel out the multiplication.Now if you don't get how to do 3/8 / 1.5, you can change the decimal to a fraction, or a fraction to the decimal.I like fractions, so I'ma do:3/8 / 3/2Or, multiple by reciprocal.3/8 * 2/3You get 2/8 which simplifies to 1/4.
