Answer 1

LCMXHCF=Product the two numbers.

Step-by-step explanation:

HCF= 5

LCM=60

Therefore, 5x60-15x the other number.

300-15x the other number

the other number= 300/15

The other number is 20.

Answer 2

lcm x hcf =  ax b

lcm =60

hcf =5

a = 15

put the values

15 x b = 5 x 60

b= 5x60 /15

b= 20          answer is 20
