Answer:375Step-by-step explanation:There can be two approaches: Direct Method or Fraction Method.DIRECT METHOD:45 / .12First, focus on the number with a decimal point. Make it a whole number by moving the decimal point to the RIGHT!.12 -> 1.2 -> 12.0Note: 12.0 and 12 are the same!Since in this case you move the decimal point to the right, two times, you will put two zeroes on the number without a decimal point.45 -> 4500Therefore, your solution will now be:4500 / 12After this, just proceed with long division and you'll be fine. (I trust that you can do it yourself)FRACTION METHOD:45 / .12Note: .12 is the same as 12/100Why? Research on that, I just want to teach you the method.The solution will now be:45/ (12/100)This means that you're now dividing a whole number with a fraction. This means that you will reciprocate the divisor and proceed to multiplication.45 * (100/12) = 4500/12 = 375
