Understanding Division of Acreage

The video tutorial explains how to divide a nine-acre lot into smaller three-fourth acre lots. It begins by introducing the problem and suggests simplifying it by using a similar, easier problem. An example with eight acres is provided to illustrate the concept. The tutorial then returns to the original problem, explaining the mathematical steps to find the number of smaller lots. The solution involves converting division into multiplication by using the reciprocal, resulting in 12 smaller lots.

What is the main problem discussed in the video?

• Adding three-fourths of an acre to a nine-acre lot.

• Multiplying the size of a lot by three-fourths.

• Calculating the area of a nine-acre lot.

• Dividing a nine-acre lot into smaller lots of three-fourths of an acre each.

How does the video suggest simplifying the problem?

• By using a calculator.

• By solving a simpler problem first.

• By multiplying instead of dividing.

• By ignoring the smaller lots.

In the simpler problem, how many two-acre lots can be made from eight acres?

• Five

• Four

• Three

• Two

What mathematical operation is used to find the number of smaller lots?

• Division

• Addition

• Subtraction

• Multiplication

How is division by a fraction performed according to the video?

• By adding the fraction to the whole number.

• By dividing by the reciprocal of the fraction.

• By subtracting the fraction from the whole number.

• By multiplying by the reciprocal of the fraction.

What is the reciprocal of three-fourths?

• One-fourth

• Four-thirds

• Three-fourths

• Two-thirds

What is the result of multiplying nine by four-thirds?

• Twelve

• Eighteen

• Nine

• Fifteen

How many smaller lots of three-fourths of an acre can be made from nine acres?

• Ten

• Nine

• Eleven

• Twelve

What is the final conclusion of the video?

• There are 10 smaller lots of three-fourths of an acre in nine acres.

• There are 12 smaller lots of three-fourths of an acre in nine acres.

• There are 6 smaller lots of three-fourths of an acre in nine acres.

• There are 8 smaller lots of three-fourths of an acre in nine acres.
