There are only two single-digit numbers where one is 1/5 of the other. Those are 1 and 5 and they become the outside numbers. From there, it's relatively easy to multiply 5 by 3 to get 15 for the inside numbers.

Then a is d/5 = 5/5 = 1.
So abcd = 1bc5.
Finally bc = d*3 = 5*3 = 15
and so abcd = 1155.

How you know the number of decimal places that should be in the product when you multiply two decimal numbers together?
Count the number of digits after the decimal point in the first number being multiplied. Count the number of digits after the decimal point in the second number being multiplied. Add the two numbers. This is the number of digits after the decimal point in the answer. But make sure that any trailing 0s are included. To calulate 0.42 * 3.451: 41*3451 = 144942 Digits after point in first number = 2 Digits after point in second number = 3 2 + 3 = 5 So digits after point in answer = 5 So answer = 1.44942 But To calulate 0.42 * 3.45: 42*345 = 14490 <<< it is vital that the last 0 here is kept till the last stage. Digits after point in first number = 2 Digits after point in second number = 2 2 + 2 = 4 So digits after point in answer = 4 So answer = 1.4490 = 1.449
