Answer:
60
Step-by-step explanation:
12=2⋅2⋅3
15=3⋅5
We see that they both share 3 is their LCM.
We divide each number by their LCM.
123⇒4
153⇒5
We multiply these two quotients and the LCM to get our final answer:
3⋅4⋅5=60
That is our answer!
Hope this helped! :)
Answer:
k = -14
Step-by-step explanation:
We should cross-multiply
9/(k - 7) = 6 / k
9*k = 6 * (k - 7)
9k = 6k - 42
9k - 6k = -42
3k = -42
k = -14

Answer:
4/5 is grater than 45/100
Step-by-step explanation:
Why?
because in percentage you make the bottom # a 100 one of them already has that and when it has 100 on the bottom it tells you that the top # is the percentage so 45/100 is 45%
now to make 4/5 a percentage what times 5 = 100?
20 does
so you times the top and bottom by 20
4*20= 80
now your fraction is 80/100 (top # tells you the %)
it's 80%
80% is grater than 45%
