Question

2/9+5/6+1/18, 2/15+1/5+3/10==?

Answer 1

Я так поняла это два выражения?

Answer 2

To solve these arithmetic expressions, let's find the common denominators and then add the fractions.

1. Expression: 2/9 + 5/6 + 1/18

To find the common denominator, we need to find the least common multiple (LCM) of 9, 6, and 18, which is 18.

Now, we can convert each fraction to have a denominator of 18:

2/9 = (2/9) * (2/2) = 4/18 5/6 = (5/6) * (3/3) = 15/18 1/18 (already in the desired form)

Adding the fractions:

4/18 + 15/18 + 1/18 = (4 + 15 + 1)/18 = 20/18

Simplifying the fraction:

20/18 = (10/9) * (2/2) = 10/9

Therefore, the value of the first expression 2/9 + 5/6 + 1/18 is equal to 10/9.

2. Expression: 2/15 + 1/5 + 3/10

To find the common denominator, we need to find the least common multiple (LCM) of 15, 5, and 10, which is 30.

Now, we can convert each fraction to have a denominator of 30:

2/15 = (2/15) * (2/2) = 4/30 1/5 = (1/5) * (6/6) = 6/30 3/10 = (3/10) * (3/3) = 9/30

Adding the fractions:

4/30 + 6/30 + 9/30 = (4 + 6 + 9)/30 = 19/30

Therefore, the value of the second expression 2/15 + 1/5 + 3/10 is equal to 19/30.
