Greetings, please pay attention to the steps the problem so you can better understand this very simple material, cheers!
To work out 2/7 + 1/5, we need to find a common denominator for the fractions.
The common denominator is the smallest number that both denominators (the bottom numbers) can evenly divide into. In this case, the common denominator is 35, because both 7 and 5 can evenly divide into it.
Now, we need to make the numerators (the top numbers) match the common denominator.
To do this, we need to multiply the numerator and denominator of each fraction by the same number that will make the denominator equal to 35.
For 2/7, we multiply the numerator and denominator by 5 to get 10/35.
For 1/5, we multiply the numerator and denominator by 7 to get 7/35.
Now that the fractions have the same denominator, we can add the numerators together:
10/35 + 7/35 = 17/35.
So, 2/7 + 1/5 equals 17/35.
