Answer: 60.528
Solve:
01.94 Line up the decimal points
x 31.20
-----------
605280
In 1.94, move the decimal place to the end, which is moving it 2 places. In 31.20, move the decimal place to the end, which is also moving it 2 places. So in total, you've moved it 4 places. In your answer, move the decimal place 4 places to the right.
605280 becomes 60.5280, which is 60.528
More thorough solving:
01.94
x 31.20
--------
0000 (Multiply 0 and 4, 0 and 9, 0 and 1, & 0 and 0)
03880 ←(Multiply 2 and 4, 2 and 9, 2 and 1, & 2 and 0)
019400 ←(Multiply 1 and 4, 1 and 9, 1 and 1, & 1 and 0)
0582000 ←(Multiply 3 and 4, 3 and 9, 3 and 1 & 3 and 0)
60.5280 (You get this when you add the numbers and place the decimal)
Now you're probably wondering where all of the zeroes from the right came from (the zeros that are bolded).
When you finish multiplying with the zero in the number 31.20,
you add a zero on the next line when you start multiplying with the other numbers.
Add one zero because it's the first number on the right.
When you finish multiplying with the 2, add 2 zeros on the line and start multiplying again.
Add two zeroes because it's the second number on the right.
Do the same for when you finish multplying with the 1, except add 3 zeroes and finish multiplying.
Add three zeroes because it's the third number on the right.
Now I know I didn't explain this in a good way, and I'm really sorry.
I'm just not able to take a picture of my work and show it, or make a video and link it or something.
I really recommend getting a teacher to help you or watching a video on how to multiply decimals.
But overall, I wish you luck! :)
