Solve the following exercise:
Let's try to find the least common denominator between 4 and 8
To find the least common denominator, we need to find a number that is divisible by both 4 and 8
In this case, the common denominator is 8
Now we'll multiply each fraction by the appropriate number to reach the denominator 8
We'll multiply the first fraction by 2
We'll multiply the second fraction by 1
Now we'll combine and get:
Without calculating, determine whether the quotient in the division exercise is less than 1 or not:
\( 5:6= \)
Because fractions represent parts of different-sized wholes. Adding is like adding 1 quarter to 6 eighths - you need the same size pieces first!
Look for the smallest number both denominators divide into evenly. Since 8 ÷ 4 = 2 and 8 ÷ 8 = 1, the LCD of 4 and 8 is 8.
Yes! When converting to eighths, multiply both numerator and denominator: . This keeps the fraction's value the same.
That's perfectly normal! When adding fractions, you can get improper fractions (numerator larger than denominator) or whole numbers like we got here: .
Always! Check if your answer can be reduced. Here, is already in simplest form since any number divided by itself equals 1.
