Answer 1

Ответ:

Пошаговое объяснение:

1) $\frac{13}{14} + \frac{1}{15}$ (домножаем первую дробь на 15, вторую на 14) =  $\frac{195}{210} + \frac{14}{210} = \frac{209}{210}$

2) $\frac{9}{10} + \frac{1}{100}$ ( первую дробь домножаем на 10) =$\frac{90}{10} + \frac{1}{100} = \frac{91}{100}$

3) $\frac{24}{25} + \frac{1}{4}$ ( первую на 4, вторую на 25) = $\frac{96}{100} + \frac{25}{100} = \frac{121}{100}$

4) $\frac{7}{8} + \frac{1}{6}$ ( первую на 3, вторую на 4) = $\frac{21}{24} + \frac{4}{24} = \frac{25}{24}$

Answer 2

1) To add the fractions 13/14 and 1/15, we need to find a common denominator. The least common multiple (LCM) of 14 and 15 is 210. We can convert both fractions to have a denominator of 210 and then add the numerators.

Converting 13/14 to have a denominator of 210: (13/14) * (15/15) = 195/210

Converting 1/15 to have a denominator of 210: (1/15) * (14/14) = 14/210

Adding the numerators: 195/210 + 14/210 = 209/210

So, 13/14 + 1/15 = 209/210.

2) To add the fractions 9/10 and 1/100, we need to find a common denominator. The least common multiple (LCM) of 10 and 100 is 100. We can convert both fractions to have a denominator of 100 and then add the numerators.

Converting 9/10 to have a denominator of 100: (9/10) * (10/10) = 90/100

Converting 1/100 to have a denominator of 100: (1/100) * (100/100) = 1/100

Adding the numerators: 90/100 + 1/100 = 91/100

So, 9/10 + 1/100 = 91/100.

3) To add the fractions 24/25 and 1/4, we need to find a common denominator. The least common multiple (LCM) of 25 and 4 is 100. We can convert both fractions to have a denominator of 100 and then add the numerators.

Converting 24/25 to have a denominator of 100: (24/25) * (4/4) = 96/100

Converting 1/4 to have a denominator of 100: (1/4) * (25/25) = 25/100

Adding the numerators: 96/100 + 25/100 = 121/100

So, 24/25 + 1/4 = 121/100.

4) To add the fractions 7/8 and 1/6, we need to find a common denominator. The least common multiple (LCM) of 8 and 6 is 24. We can convert both fractions to have a denominator of 24 and then add the numerators.

Converting 7/8 to have a denominator of 24: (7/8) * (3/3) = 21/24

Converting 1/6 to have a denominator of 24: (1/6) * (4/4) = 4/24

Adding the numerators: 21/24 + 4/24 = 25/24

So, 7/8 + 1/6 = 25/24.
