What is the LCM of CD and df?
The LCM is cdf
What is the LCM of ab and bc?
The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. In this case, the LCM of ab and bc would be the product of the two numbers divided by their greatest common divisor (GCD), which is b. Therefore, the LCM of ab and bc is abc.
If BC 8.3 CD 6.7 and AD 11.6 what is AB to the nearest tenth?
That will depend on what type of quadrilateral it is and other information such as its area.
Is the difference of two rational numbers always a rational number?
Yes. Since they are rational numbers, let's call the first one a/b and the second one c/d where a,b,c, and d are integers. Now we can subtract by finding a common denominator. Let's use bd. So we have ad/bd-cb/bc= (ad-bc)/CD which is rational since we know ad and bc are integers being the product of integers and CD is also an integers. Call ad-bd=P and call CD=Q where P and Q are integers. We now see the difference is of two rationals is rational.
What is the LCM of 26 and 78?
The LCM is 78.
