Understanding Division with Decimal Points

Introduction to Division Concepts

• Daniel Carreón introduces the topic of division with decimal points, emphasizing the importance of understanding basic division components.

• Key terms are defined:

• "Óvalo" refers to the division symbol.

• "Dividendo" is the number being divided.

• "Divisor" is the number outside the division symbol.

• "Residuo" is the remainder, and "cociente" is the quotient.

Steps for Dividing with Decimals

• To perform a division where the divisor has a decimal point, it must be converted into an integer by moving its decimal point to the right.

• The same number of places that you move in the divisor should also be applied to the dividend. This ensures both numbers remain proportional.

Example Problem: 35.1 ÷ 0.15

• In this example, moving the decimal point in 0.15 two places to convert it into an integer (15), requires moving 35.1's decimal point similarly, resulting in 3510 ÷ 15.

• The process begins by determining how many times 15 fits into each part of 3510:

• For '3', it fits '0' times; for '35', it fits '2' times (30); then subtracting gives a remainder of '5'.

Continuing with Example Problem

• Next, bringing down '1' results in checking how many times '15' fits into '51', which is '3' times (45), leaving a remainder of '6'.

• Finally, bringing down '0' leads to checking how many times ‘15’ fits into ‘60’, which is exactly ‘4’ times (60), resulting in no remainder and concluding that 3510/15 = 234 .

Additional Example: Dividing by a Larger Decimal

• Another example presented involves dividing 2016 by 2.8. The decimal in 2.8 moves one place right to become 28.

• Consequently, 2016's decimal also shifts one place right leading to 2016 ÷ 28.

Solving Further Examples

• In this case:

• For ‘20’, it still doesn’t fit; thus another zero is placed above until reaching ‘201’.

• Here, ’28’ goes into ’201’ seven times (196), leaving a remainder of ’5’.

Finalizing Results from Examples

• Bringing down ‘6’ allows checking how many times ’28’ fits into ’56’, which is exactly two times (56), yielding no remainder and confirming that 2016/28 = 72 .

Last Example: Dividing Decimals Again

• A final problem involves dividing 112.5 by 4.5. Moving one place converts it to 45.
