An easy way to do questions like these is by converting the fractions into decimals, at least I used to find it easier by doing so when I first encountered them.
So,
7/9 as a decimal is 0.77
1/3 as a decimal is 0.33
You can do;
0.77 - 0.33
You are left with;
0.44
Which in it's simplest fraction form is;
11/25.
Your answer is 11/25.
I hope this helped, if you need help with understanding how to conver then do let me know! ;3
Answer:
x = 9 or x = 0
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 4 x - 5 x = 0
x^2 - 4 x - 5 x = x^2 - 9 x:
x^2 - 9 x = 0
Factor x from the left hand side:
x (x - 9) = 0
Split into two equations:
x - 9 = 0 or x = 0
Add 9 to both sides:
Answer: x = 9 or x = 0
2x² + 3x - 5 = 0
a=2, b=3, c=-5
D = b² - 4ac = 3² - 4*2*(-5) = 9 + 40 = 49
If you are given the volume then you can solve
v=volume
h=height
l=legnth
w=width
hlw means h times l times w
v=hlw
so to find height divide both sdie sby lw
v/lw=hlw/lw
v/(lw)=h
so just divide volume by the quantity lengh times width
if you were given the volume
Answer: 
Step-by-step explanation:
When we throw a die , Total outcomes =6
When we throw 3 dice , Total outcomes = 6 x 6 x 6 = 216 [by fundamental counting principle]
Given : Three fair dice are rolled, one red, one green and one blue.
Favorable outcomes : When the upturned faces of the three dice are all of different numbers i.e. no repetition of numbers allowed
By Permutations , the number of favorable outcomes = 
The probability that the upturned faces of the three dice are all of different numbers = 
The probability that the upturned faces of the three dice are all of different numbers is .
