MULTIPLICATION

OF

DECIMALS

Math VI

IVY ROSE P. PASTOR

Master Teacher II

Let’s do the multiplication

of

decimals. Who can tell me

how to multiply decimals?

Yes, Mylin Jessica

Razel!!!

To multiply decimals, we do the same rule in multiplication of

whole number but in the product, we count the number of

decimal places in the multiplicand and multiplier and then we

move the decimal according to the total places of the

multiplicand and multiplier from right to left.

Can you show us

an example on the

board Arah Li?

Very good!

Now, how many decimal places are there in 0.11 x 1.54.

Emer?

4 decimal

places

Very good! How about in

0.0006 x 15. 32 . Rose.

6 decimal

places

I believe that you are now ready for

more challenges. Good Luck!!!!
