Question

1)7/10+1 5/10 ? 2) 11 3/100 + 8 9/100 Даю 10б пожалуйства помогите

Answer 1

Ответ:

$\frac{7}{10} + 1 \frac{5}{10} = 1 \frac{12}{10} = 2 \frac{2}{10} = 2 \frac{1}{5}$

$11 \frac{3}{100} + 8 \frac{9}{100} = 19 \frac{12}{100} = 19 \frac{3}{25}$

Answer 2

1. To add the fractions 7/10 and 1 5/10, we need to find a common denominator. In this case, the denominator is already the same (10).

The numerator of the mixed number 1 5/10 can be converted to an improper fraction by multiplying the whole number (1) by the denominator (10) and adding the numerator (5). So, 1 5/10 is equal to (1 * 10 + 5)/10, which simplifies to 15/10.

Now we can add the fractions: 7/10 + 15/10 = (7 + 15)/10 = 22/10.

However, 22/10 is an improper fraction. We can simplify it by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 2 in this case: 22/10 = (2 * 11)/(2 * 5) = 11/5.

Therefore, the result is 11/5.

2. To add the fractions 11 3/100 and 8 9/100, we can follow a similar approach.

First, convert the mixed numbers to improper fractions: 11 3/100 = (11 * 100 + 3)/100 = 1103/100, 8 9/100 = (8 * 100 + 9)/100 = 809/100.

Now, we can add the fractions: 1103/100 + 809/100 = (1103 + 809)/100 = 1912/100.

Simplifying the fraction by dividing both the numerator and the denominator by their GCD (which is 4 in this case), we get: 1912/100 = (4 * 478)/(4 * 25) = 478/25.

Therefore, the result is 478/25.
