To solve the addition of , we will follow these steps:
Now, let's perform the calculations:
Step 1: Convert to improper fractions.
becomes because .
becomes because .
Step 2: Find a common denominator.
The least common denominator of 2 and 7 is 14. We convert and to have this common denominator:
(because )
(because )
Step 3: Add the resulting fractions.
Step 4: Convert the improper fraction back to a mixed number.
can be expressed as because 79 divided by 14 is 5 with a remainder of 9.
Therefore, the solution to the problem is .
\( 5:\frac{2}{5}= \)
You can add whole numbers separately, but the fractions need a common denominator first! requires converting both to fourteenths before adding.
Multiply the whole number by the denominator, then add the numerator. For : (2 × 2) + 1 = 5, so it becomes .
Since 2 and 7 are both prime numbers, their LCD is simply their product: 2 × 7 = 14. When denominators share no common factors, multiply them together!
Divide the numerator by the denominator. For :
Yes, always check! In this case, cannot be simplified further since 9 and 14 share no common factors other than 1.
While possible, it's not recommended here because creates a repeating decimal (0.142857...), making the calculation messy. Stick with fractions for exact answers!
