Step-by-step explanation:
the lowest common denominator (LCD) is the lowest common multiple (LCM) of the denominator numbers (the ones at the bottom of the fractions).
finding the LCM of 9 and 12 using the prime factor method :
9 = 3×3
12 = 2×2×3
the LCM is the combination of the longest chains per prime factor. which means we have 2×2 and 3×3 as longest chains for 2 and 3.
LCD = LCM = 2×2×3×3 = 36
2/9 turns into x/36 by multiplying by 4/4 :
2/9 × 4/4 = 8/36
5/12 turns into x/36 by multiplying by 3/3 :
5/12 × 3/3 = 15/36
so, the third answer option is correct.

Answer:256 cows
Step-by-step explanation:
Let the total cow be a
3/4 of a
3/4 x a=3a/4
Remainder= a-3a/4=a/4
Remainder=a/4
3/4 Of The remainder
3/4 of a/4
3/4 x a/4=3a/16
New remainder will be
a/4-3a/16=a/16
New remainder is a/16
Therefore: a/16=16
Cross multiplying we get
a=16x16
a=256

Answer:
The answer to your question is 5 weeks
Step-by-step explanation:
Data
Ryan Miles
$150 $50
each week = $40 each week = $60
x = savings
y = time in weeks
Process
1.- Write an equation for Ryan savings
x = 40y + 150
2.- Write an equation for Miles savings
x = 60y + 50
3.- Solve the system by Equality
40y + 150 = 60y + 50
- Solve for y
40y - 60y = 50 - 150
-20y = -100
y = -100 / -20
y = 5
4.- Conclusion
After 5 weeks, they will have the same amount of money.
