Multippcation with traipng zeros: Problem type 1

Traipng zeros

The zeros at the end of a number are known as traipng zeros.

For example

The number of traipng zeros in 80 is one.

The number of traipng zeros in 6000 is three.

The number of traipng zeros in 100890 is just one.

Multippcation of numbers involving traipng zeros

Some Examples: Multiply 50 × 3; Multiply 200 × 6; Multiply 9 × 10,000

Multiply 70 × 6

Solution

Step 1:

Here we multiply 7 × 6 first

7 × 6 = 42

70 × 6 = 42__

Step 2:

Then we write a 0 at the end.

70 × 6 = 420

Multiply 600 × 4

Solution

Step 1:

Here we multiply 6 × 4 first

6 × 4 = 42

600 × 4 = 24__

Step 2:

Then we write two zeros at the end.

600 × 4 = 2400
