### Step 1

Multiply as you normally would

27

x

35

945

### Step 2

Count the number of digits

behind a decimal point in the

problem. This one has two

digits behind the decimal

point, the 7 and the 5.

2.7 x 3.5 =

### Step 3

Put the decimal point in the

digits behind a decimal point, your

answer should have 2 digits

behind a decimal point.

had 3 digits behind a

decimal point, your

answer should have 3 digits

behind a decimal point.

had 4 digits behind a

decimal point, your

answer should have 4 digits

behind a decimal point.

### Step 4

Add zeros if needed.
