Answer:
LCM (8,10) = 2 × 2 × 2 × 5 = 40
Step-by-step explanation:
Least common multiple is the smallest number that is multiple of both the given numbers.
Example: LCM of 2 and 3 is 6 .
6 is a multiple of both 2 and 3 .
 Given numbers are 8 and 10
First write both in factor form,
⇒ 8 = 2 × 2 × 2 
⇒ 10 = 2 × 5
We find LCM by writing common terms one times and multiplying all terms together, 
Here, 2 is common to both 8 and 10 so we write it once only.
Thus, LCM (8,10) = 2 × 2 × 2 × 5 = 40.
 
        
             
        
        
        
Answer:
The value of π = 22/7 = 3.14
 
So here the Equation given we can examine those
 
1. 3π -1 > 9 
=> (3 * 3.14 ) -1 > 9
=> 9.42 – 1 > 9
=> 8.42 > 9 , which is false
 
2. 7π > 21
=> (7 * 3.14) > 21
=> 21.98 > 21 , Which is true
 
3. π + 4 < 7
=> 3.14 + 4 <7
=> 7.14 <7 , Which is false
 
4. (12/ 4π) > 1
=> {12/ (4 * 3.14)} > 1
=> (12/12.56) > 1
=> 0.955 > 1 , Which is false
