Step-by-step explanation:

Answer 2

Answer:

1.5, 7

2.The first multiple of 7 under 10 is 7 itself and over 40 is 42. So the multiple of 7 in between will be 14, 21, 28 and 35.

3. yes

4. 60

5.he HCF of two numbers is 6

The LCM of two numbers is 36

Let the numbers be a and b

According to question

(a×b) = HCF×LCM  

HERE a = 12 , Hcf = 6 , LCM = 36  

WE have to find b  

12×b = 6×36

b= 6× 36/12  

b = 18.

Therefore answer: - The other number is 18.
