Answer:
X = 119
Step-by-step explanation:
Step 1: Given
Y = -5 X = 7
Y = -85 X = n
Step 2:
-85 ÷ -5 = 17
Step 3:
17 × 7 = 119
Answer:
Y = -5 X = 7
Y = -85 X = 119
n = 119
In reality your common denominator should be the Least Common Multiple. The LCM is the product of highest occurring primes of the numbers prime factorizations...
4=2*2, and 12=2*2*3. So the LCM is 2*2*3=12 Now that you know what the least common multiple is we can say that:
(3/4)(3/3)+5/12
9/12+5/12
(9+5)/12
14/12
7/6 which should be converted to a mixed number as this is an improper fraction...
(6+1)/6
1+1/6
1 1/6
