Answer:
10.8
Step-by-step explanation:
Given that there are two numbers whose sum is equal to 27, you can set up an equation:
x + y = 27, where 'x' is the first number and 'y' is the second number
'The first number is 60% of the sum.' Set up another equation for the first number:
x = 27(0.6) or x = 16.2
Since x = 16.2, plug this number into the first equation and solve for 'y':
16.2 + y = 27
y = 10.8
