1.2 Multiplying decimals

Just follow these steps:

1. Multiply normally, ignoring the decimal points.

2. Then put the decimal point in the answer - it will have as many decimal places as the two original numbers combined.

Multiply as usual, ignoring the decimals

Count the number of digits after the decimal point in both numbers in the question -----> here there is one

Put the decimal point into your answer so that it also has only one decimal place

Notice, there is one decimal place in the answer (and one decimal place in the numbers in the question!)

1. Multiply the numbers ignoring the decimal places

2. Position the decimal place in your answer so that it has the same number of decimal places as the numbers in the question

Notice, there are four decimal places in the numbers in the question, and four decimal places in the answer!

Its your turn!
