Hi!
First let's find the LCD of all of the fractions, and change all of them.
The LCD of 3, 6, 8, and 10 is 120.
Now change all of the fractions.
120/3 = 40
2 x 40 = 80
80/120
120/6 = 20
7 x 20 = 140
140/120
120/8 = 15
1 x 15 = 15
15/120
120/10 = 12
9 x 12 = 108
108/120
Now, line up all of the new fractions, and put them in order from least to greatest.
80/120, 140/120, 15/120, 108/120
15/120, 80/120, 108/120, 140/120
1/8, 2/3, 9/10, 7/6
^the answer
Hope this helps! :)
Answer:
What are the laws of indices?
Laws of indices provide us with rules for simplifying calculations or expressions involving powers of the same base. This means that the larger number or letter must be the same.
Step-by-step explanation:
The first law: multiplication
The second law: division
The third law: brackets
Negative powers
Power of zero
Fractional powers
Answer:
x^2+7x +49/4 and (x+7/2)^2
x^2+bx +b²/4 and (x+b/2)^2
Step-by-step explanation:
Given the expression
x^2+7x+c
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = 7/2
Taking the square of the result
Square of the result = (7/2)^2
Hence c = (7/2)^2
The expression becomes;
x^2 + 7x + (7/2)^2
= x^2+7x +49/4
= (x+7/2)^2
For x^2+bx+d
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = b/2
Taking the square of the result
Square of the result = (b/2)^2
Hence d = (b/2)^2
The expression becomes;
x^2 + bx + (b/2)^2
= x^2+bx +b²/4
= (x+b/2)^2
