The lcd of two fractions is always greater than the denominator of the fractions. Reasonable or not?

2 answers:

7 0

Lcd means least common denomenators
it is normally used to combine fractions with differnt denomenators

I can show 2 disproofs

so
they can be equal
conside
3/4 and 5/8
lcd is 8, 8>8 is false
not reasnable

they can be less if they arenot simplified
example
4/8 and 24/16
lcd is 4

not reasonable

It is not reasonable.
The LCD can be less than the denominators if the fractions are not in simplest form but the LCD can be equal to one of the fractions even if they are in simplest form, for example:
3/4 and 1/2

Hope this helps :)

NikAS [45]

Answer:

Colin spends 1/8 of an hour practicing each song

Step-by-step explanation:

Colin's piano lesson is 3/4 of an hour, long.

In that period, he practices 6 different songs, spending an equal amount of time on each one.

This means that each song gets the sixth part of the lesson duration. The fraction that expresses that amount is:

$\displaystyle \frac{\frac{3}{4}}{6}=\frac{3}{24}=\frac{1}{8}$

Colin spends 1/8 of an hour practicing each song

Which of the following situations would best be modeled by a discrete relationship? a. A teacher counts the number of students i

Nata [24]

Answer:

Option d is correct.

Step-by-step explanation:

Discrete values are those which take an integer value not in fraction.

Option A is discrete because there will be certain number of students in class say 20 or 30

We can not have 20.5 students

Therefore, option a is correct.

Option B is not discrete because many people can have age say 65 and a half years and weight can be in decimals say 50.5 kgs.

Option C is correct because he is saving a proper integer number of money.

Therefore, option d is correct that is both A and C are correct.
