to get the LCD we should start by doing a quick prime factoring of each denominator, as you see in the picture below.
the factors in red are the common factors to all values, and they are used in the LCD only once, the other not common factors in blue, they're used in the LCD.
Answer:
14/25, 6/25, 1/5, 3/5
Step-by-step explanation:
Answer: 6 nickels and 9 dimes
Step-by-step explanation:
15 coins - 3 extra dimes = 12
12 / 2 = 6
6 nickels
6 + 3 = 9 dimes
You reduce the fraction which would be 9b-1/3=5b+ 5/3
Then you move the variable to the left side and change its sign 9b-5b-1/3=5/3 then move the constant to the right side 9b-5b=5/3+1/3
Then collect the terms 4b= 5/3 + 1/3 add the fractions 4b = 2
Divide both sides of the equation which is b= 1/2
