In decimal numbers we have this rule :
If we multiply a decimal number by 10, 100, 1000... , then we move the decimal point by 1, 2 ,3 ,.... digits to the right side. It depends on the number of zeros .
If we divide a decimal number by 10, 100, 1000... , then we move the decimal point by 1, 2 ,3 ,.... digits to the left side. It depends on the number of zeros .
So in multiplication we move to the right side.
Multiplied by 10 - moves one place to the right side
Multiplied by 100 - moves two places to the right side.
So answer is fourth option when we multiply decimal number by 100, it will move two spaces to the right side.
