Answer 2

The ratio between the LCM and HCF of 5 15 and 20 is​ 12:1

Step-by-step explanation:

Numbers : 5 ,15 , 20

HCF:

5 | 5        5 | 15          5 | 20

  |  1        3 | 3            2 | 4

                 | 1             2 |  2

                                    | 1

$5 = 5 \times 1$

$15 = 5 \times 3$

$20 = 5 \times 2 \times$

HCF = 5

LCM :

5 | 5 , 15 , 20

3 | 1 , 3 , 4

4 |  1 ,1 , 4

  |  1 ,1 ,1

LCM = $5 \times 3 \times 4 = 60$

ratio = 60:5 = 12:1

The ratio between the LCM and HCF of 5 15 and 20 is​ 12:1
