Multiply decimals by 10 100 1000
Due to the fact that our number system is base 10, multiplying decimal numbers by powers of 10 is relatively simple. The digits of the number move around, and there are maybe zeros to add or remove, but the other digits all stay the same. Remember that when we multiply numbers by any number greater than 1 they get bigger so check this once your done.
Let's get our terms straight.
factor x factor = product
23.45 x 100 = 2345
So for the sum 23.45 x 100 = 2345,
- 23.45 and 100 are the factors
- 2345 is the product
When we multiply by 10 the product is 10x bigger than the initial factor.
When we multiply by 1000 the product is 1000x bigger than the factor.
Note that in the example above, the decimal point of the product is not written down because the product is an integer.
Multiply decimals by 10, 100 or 1000 : move the digits
Write the digital factor to be multiplied by a power of 10 down. Keep the digital point still and move all the digits of the digital factor to the left around it. If we are multipling by 10, all the digits move 1 column to the left. If we are multipling by 100, all the digits will move 2 columns to the left, and for multipling by 1000, it is 3 columns.
7.438 x 10 = 74.38
7.438 x 100 = 743.8
7.438 x 1000 = 7438
Alternative method : move the point
Another method is to keep the digits of the decimal number static and move the decimal point to the right. If the factor is 100 move it two places to the right, one for each of the zeros in 100. If you are not writing numbers down, this can be an easier method to visualise in your head.
0.0671 x 10 = 0.671
0.0671 x 100 = 6.71
0.0671 x 1000 = 67.1
Check your answer
Multiplying by a number greater than 1? Then product should be bigger than the original number!
Remember too that multiplying and dividing are inverse operations so you can always check a multiplication by dividing the product by whatever power of 10 you multiplied by and make sure you get the original value returned.
0.0671 x 100 = 6.71
6.71 ÷ 100 = 0.0671
With our Mix and match math game you will be practicing the topic "Multiply decimals by 10 100 1000" from 6th grade / Number / Decimals / Decimals. The math in this game consists of 16 questions that ask you to multiply by powers of 10 up to 1000 by moving the digits the correct number of columns to the left.
In this game we are in a room with lots of toys - and the room needs clearing up - you need to put the play blocks back in the right boxes to tidy the room and win the game...but which is the right box for each block? Well, you can work that out by comparing the question on the block with the math answer on each of the boxes - you should drag the question block into the box whose math answer matches the picture question.
You can listen to the spoken math answer by clicking on the individual boxes. There are 5 blocks to clear up - but if you put them in the wrong boxes, there will be more... Anyway, tidy is good and practicing math is better so start now and see how you get on...
This game reinforces the math you learned or revised in the lesson by asking you to match each question to the correct answer. If you are older you may not like the childish reference to toys, but don't worry - there are other games to play, and who knows - you might like a trip down memory lane?
