- Mike made 5/6 of his free throw attempts
- Lisa made 7/9 of her free throw attempts
LCM of Denominator
To bring the denominator, we need to take the LCM of the denominator, therefore,
we know that the LCM of 6 and 9 is 18. therefore,
Thus,
- Mike made

Answer:
B and C
Step-by-step explanation:
First you have to find a common denominator which would be 18. Then you need to multiply the denominators to get to 18. 6x3 and 9x2. Now whatever you do to the bottom you have to do to the top. So you would mutiply 5x3 and 7x2. The fractions you are left with are, 14/18 and 15/18.

Answer:
X= -46/7
Step-by-step explanation:
step1: left part times 15 is 3(X+3)-5(2X-1)
step2: right part times 15 is 60
step3: 3(X+3)-5(2X-1)=60
step4: 3X+9-10X+5=60
