Pair of numbers

What is the value of the smaller of a pair of numbers for which their sum is 78 and their division quotients are 0.3?

Correct answer:

a =  18

Step-by-step explanation:

a+b = 78 a/b = 0.3  a = 0.3 b a=0.3 (78a) 1.3a=23.4 1013a=5117 13a=234 a=234/13=18  b=78a=7818=60 a=18

a = 0.3 · (78-a)

1.3a = 23.4


a = 23.4/1.3 = 18

a = 18
