Write two different mixed numbers where the LCD (lowest common denominator) is 12

Mars2501 [29]

Two mixed numbers as $\frac{5}{6}$ and $\frac{5}{12}$ the least common denominator (LCD) is 12.

<u>Step-by-step explanation:</u>

The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. Also known as the lowest common denominator, it is the lowest number you can use in the denominator to create a set of equivalent fractions that all have the same denominator.

<u>Steps to find the LCD of fractions, integers and mixed numbers:</u>

Convert integers and mixed numbers to improper fractions
Find the LCD of all the fractions
Rewrite fractions as equivalent fractions using the LCD

Let's us have two mixed numbers as $\frac{5}{6}$ and $\frac{5}{12}$ .

Equivalent Fractions with the LCD

$\frac{5}{6}$ = $\frac{10}{12}$

$\frac{5}{12}$ = $\frac{5}{12}$

For the denominators (6, 12) the least common multiple (LCM) is 12. Therefore, the least common denominator (LCD) is 12.

In ABC, CT is a median. What is the measure of AB?

Step2247 [10]

Answer:

AB = 102

Step-by-step explanation:

the median CT bisects the side AB at T , then

BT = AT , that is

7x + 9 = 5x + 21 ( subtract 5x from both sides )

2x + 9 = 21 ( subtract 9 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

then

AB = 5x + 21 + 7x + 9 = 12x + 30 = 12(6) + 30 = 72 + 30 = 102

Heather has divided $5600 between two investments, one paying 9% the other paying 5%. If the return investment is $396, how much

Westkost [7]

Answer:

x = 2700 y=2900

Step-by-step explanation:

x+y = 5600

5/100 x + 9/100 y = 396

x+y=5600

5x+9y=39600

5x+5y = 28000

5x+9y=39600

-4y = -11600

y= 2900

x = 5600-2900 = 2700

a group of students decided to collect as many paise (1/100 RS.) from each member of the group as is the number of members. If t

Softa [21]

Answer:

Let the no. Of members be x

Rs. 59.29 = 5929 paise

5929/x = x

x^2 = 5929

Therefore x = 77

No. Of members = 77

Hope this helps!
