How do you calculate the number of items that can be made with a limited resource?

Back

Divide the total amount of the resource by the amount needed for one item, and use the whole number part of the quotient.

Front

If you have 120 minutes and each call takes 7 minutes, how do you find out how many calls you can make?

Back

Divide 120 by 7. The quotient gives the number of full calls, and the remainder shows leftover time.

Front

What does it mean to use the remainder as part of the answer?

Back

It means to consider the leftover amount when determining how many complete items can be made.

Front

How many flashlights can be powered with 27 batteries if each flashlight needs 5 batteries?

What is the formula to find the number of complete groups in division?

Back

Number of complete groups = Total amount ÷ Size of each group.

Front

In the context of division, what does 'dropping the remainder' mean?

Back

It means ignoring the leftover amount and only considering the whole number part of the quotient.

Front

When might you round the quotient to the next greater whole number?

Back

When the remainder is significant enough to indicate that another complete item can be made.

Front

What is the importance of understanding remainders in real-life situations?

Back

Understanding remainders helps in making decisions about resources, such as how many items can be made or how to allocate time.
