Test: Multiplication and Division - Year 4 MCQ

Dividing 224 by 7 gives a quotient of 32 since 7 × 32 = 224. This example illustrates how division can be used to find how many groups of a certain size can be formed from a total amount.

When you multiply the ones place and get 54, you write down 4 in the ones column and carry over 5 to the tens column. This carrying process is crucial for maintaining accuracy in multi-digit multiplication.

The term "quotient" refers to the result of the division. It is the number of times the divisor can fit into the dividend without exceeding it. Understanding this term is fundamental in mastering division concepts.

The first step in the column method for multiplication is to write the numbers vertically, with the multi-digit number on top and the 1-digit number below. This organization allows for a structured approach to multiplication, facilitating easy carrying and addition of products.

In this case, if 38 divided by a 1-digit number gives a quotient of 6 with a remainder of 2, the divisor must be 6. This is because 6 × 6 = 36, and adding the remainder of 2 gives you 38. This illustrates the connection between division, multiplication, and the concept of remainders.

After calculating the first part of a division problem using the splitting method, you must combine the quotients obtained from each part. This step is crucial for obtaining the final quotient and remainder accurately.

Estimation assists in multiplication by helping to verify the accuracy of the final answer. For instance, estimating the numbers before performing the multiplication can offer a quick check to see if the calculated product is reasonable.

Rounding up or down after division helps provide a sensible answer to a problem, especially in practical scenarios where exact numbers may not be necessary or possible, such as determining the number of teams or items needed.

To verify if the answer to a multiplication problem is reasonable, you should estimate the multiplication. This involves rounding the numbers being multiplied to make mental calculations easier, allowing you to quickly assess whether the final product is in a reasonable range.

When dividing 75 by 4 using the method of splitting the dividend, you would find that 75 = 40 + 35. Dividing these parts gives you 10 for 40 and 8 with a remainder of 3 for 35, resulting in 18 r3.

The term "dividend" refers to the number being divided in a division operation. Understanding this term is essential for grasping the concepts of division and its components.

The maximum value of a remainder when dividing by a divisor is always one less than the divisor. Therefore, when dividing by 6, the maximum remainder is 5. This property helps in understanding the limits of division outcomes.

A practical application of division is determining how many packs of paper are needed for a project, such as calculating how many 8-plate packs would be necessary if you have 27 plates and each pack contains 8 plates. This kind of problem-solving is common in everyday situations.

The term "estimate" in multiplication refers to an approximate calculation used to verify the reasonableness of an answer. For example, rounding numbers can help quickly gauge whether the final product is realistic compared to the estimated value.

The statement that the remainder can never exceed the divisor is true. The remainder is always less than the divisor because it represents what is left over after dividing as evenly as possible.
