# Multiplication and division of decimals

Multiplication of Decimals

Multiplication of 2.8 and 7

• 2.8 × 7 (There is only one digit to the right of the decimal point in 2.8)
• 28 × 7 (Ignoring the decimals)
• 28 × 7 = 196
• Now bring the decimal back after one digit from left and thus answer is 19.6

Division of Decimals

Divide 3.4 by 2

• = Quotient
• Ignore the decimal and divide the numerator by the denominator. Here, quotient
• Since there is only one digit to the right of the decimal, put the decimal after one digit from left in the quotient. Therefore, quotient becomes 1.7
