Question

We ______ when we have to find value of many units, when the value of one is known.​

Answer 1

Answer:

We multiply when we have to find value of many units, when the value of one is known.​

Step-by-step explanation:

• Multiplication is one of the important arithmetic operations among addition, subtraction, multiplication and division.
• Multiplication is widely used in day to day life.
• When the amount of one quantity is known and the amount of many such quantities is to be calculated, then we multiply the amount of one quantity to the number of quantities. The resulting product of both is our answer.
• Ex. The rate of one pencil is Rs. $4$. What will be cost of such $11$ pencils?

• In this case, rate of one pencil is given and we have to find the cost of $11$ pencils.
• So, Cost of  pencil = Cost of one pencil*number of pencil

                              = $4*11$

                              = Rs. $44$

• Hence, We multiply when we have to find value of many units, when the value of one is known.​
