To do this problem, you gotta cross-multiply. SO, \frac{12}{21} multiplied by \frac{14}{3}

12 times 14 = 168
21 times 3 = 63
Then the final answer is \frac{168}{3}

What is the lmc of two numbers that have no common factors greater then 1
Luba_88 [7]
We can take prime numbers so they don't have a common factor other than 1.

3, and 5.

So we have to list the multiples to find the LCM

3: 3, 6, 9, 12, 15, 18
5: 5, 10, 15, 20, 25

15 is the LCM of 3 and 5

So, you can notice that if two numbers, lets call them a and b, have no common factor, then a \times b is the LCM.

Hope that helped :)

Ksenya-84 [330]

Answer:

90°

Step-by-step explanation:

since PQ is the diameter of the circle, m <em>L</em><em> </em>PRQ = ½ × 180° = 90°.

so, as a supplementary to <em>L</em><em> </em>PRQ, the value of angle QRS = 180 - m <em>L</em><em> </em>PRQ = 180-90 =90°
