Write equivalent fractions for 11/12 and 9/10 using the least common denominator

55/60 and 54/60

Step-by-step explanation:

The LCD is 60. Multiply numerators and denominators. Hope this helps.

11/12 = 55/60, 9/10 = 54/60

Step-by-step explanation:

First, find what the common denominator would be. To do this, you want to find the LCM of 12 and 10, or the smallest possible number that is divisible by both 12 and 10.

This would be 60.

Next, you want to make the denominator 60.

You can do: 11/12 * 5/5 = 55/60

And: 9/10 * 6/6 = 54/60

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
