To add these mixed numbers and fractions together, you'll need to convert the mixed numbers to improper fractions, find a common denominator, and then add the fractions. Here's how you can do it step by step:
Convert the mixed numbers to improper fractions:
- 2 1/6 = (2 * 6 + 1) / 6 = 13/6
- 2 5/12 = (2 * 12 + 5) / 12 = 29/12
- 2/15 remains the same as it's already a fraction.
- 42 18/25 = (42 * 25 + 18) / 25 = 1068/25
Find a common denominator for all the fractions. In this case, the least common denominator is 180. So, we need to rewrite all the fractions with a denominator of 180:
- 13/6 = (13/6) * (30/30) = 390/180
- 29/12 = (29/12) * (15/15) = 435/180
- 2/15 = (2/15) * (12/12) = 24/180
- 1068/25 = (1068/25) * (7.2/7.2) = 18396/180
Now, all fractions have a common denominator of 180:
- 390/180
- 435/180
- 24/180
- 18396/180
Add the fractions:
(390/180) + (435/180) + (24/180) + (18396/180)
To add the fractions, you can simply add their numerators while keeping the common denominator:
(390 + 435 + 24 + 18396) / 180
Add the numerators:
19045 / 180
Simplify the fraction if possible. Both the numerator and denominator can be divided by 5:
(19045 ÷ 5) / (180 ÷ 5) = 3809/36
Further simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 1:
3809/36
So, the sum of the given mixed numbers and fractions is equal to 3809/36, which can also be expressed as an improper fraction as shown above.
