Answer:
7/12
Step-by-step explanation:
2x6 =12 for the dinominator the nummarraton is 6 +1 =7
Your answer is 3/2 i know for a fact
Let the number be x.
then the number is (x + 6)
the difference between their squares is 192
(x + 6)² - x² = 192
expanding we get;
x² + 12x + 36 - x² = 192
12x + 36 = 192
12x = 192 - 36
12x = 156
x = 13
the numbers are 13 and 19.
hope this helps, God bless!
