Convert the fractions into equivalent fractions with the same denominator.
In actually adding mixed numbers, it is easier to convert the mixed numbers into improper (top heavy) fractions, do the addition, simplify the resulting fraction and convert any resulting improper fraction back into a mixed number.

What do you do if the bottom numbers are different in fractions?
Those "bottom" numbers are called denominators. It just depends what kind of operation (add, subtract, multiply, divide) you are asked to perform with these fractions. In this case, I am going to assume that you are asked to add or subtract fractions with different denominators (bottom numbers). (In any other case, such as multiplying or dividing, the denominators need not be the same.) If this is the case, then you are going to have to find a common denominator. This can be done by finding the LCM (least common multiple) of both denominators. Example: (1/3) + (1/2) = ? Since the denominators (3 and 2) are different, you will need to find the LCM. In this case, the LCM of 3 and 2 is 6. Now, in order to make the denominators the same, you will need to multiply the 3 by 2 and the 2 by 3 to get a common denominator of 6. Now, remember that what you are doing is simply "renaming" the fraction. So, what you do to the denominator (bottom number), you must also do to the numerator (top number). You can think of it as multiplying both fractions by a fancy form of 1...which as you should know, anything times 1 is just that same number. So, multiply the first fraction by 2/2 and the second fraction by 3/3) Now you get {(1/3)*(2/2)} + {(1/2)*(3/3)} = (2/6) + (3/6) = (5/6) Hope this helps! :)
How do the output numbers from the two machines compare?
They are different and unequal.
A keycode must contain 4 letter and 3 numbers. The letters may be any letter of the alphabet. The numbers should be any number from 0 to 5. How many different keycode combination are there?

A keycode must contain 2 letters and 3 numbers. The letters may be any letter of the alphabet. The numbers should be any number from 0 to 9. How many different keycode combinations are there?
676,000 but I don’t know why
When adding or subtracting fractions what should you do first?
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
When asked to find the sum of two mixed numbers with different denominators you should before you add.?
convert both to numbers with lowest common denominator then add
What is the first thing you should look for when adding or subtracting fractions or mixed numbers?
common denominators.
How is adding rational numbers different than adding whole numbers?
Whole numbers are rational numbers with a denominator of 1. The difference with general rational numbers is that the denominators are likely to be different and they must be made the same by converting the fractions into equivalent fractions with the same denominator before the addition can be done - by adding the numerators and keeping the denominator, and simplifying (if possible) the result. With whole numbers the denominators are already the same (as 1) and so the addition can be done straight away.

At what age should a child be able to count 123?
A child should begin to be able to count to ten around age two. Children can be introduced to numbers about a year before this. However, each child learns to count at a slightly different age.
How is estimating quotients different from estimating products?
Normally when estimating quotients you should round both numbers in the same direction whereas for products you should round the two numbers in opposite directions.
