Question

11/20 * (2/11-3/8)+11/20*3/8

Answer 1

Ответ:

1/10 или 0.1

Пошаговое объяснение:

11/20×(2/11-3/8)+11/20×3/8=1/10 или 0.1

1. 2/11-3/8=16/88-33/88=-17/88
2. 11/20×(-17/88)=-17/160
3. 11/20×3/8=33/160
4. -17/160+33/160=16/160=1/10 или 0.1

Answer 2

To solve the expression, let's break it down step by step:

11/20 * (2/11 - 3/8) + 11/20 * 3/8

First, let's simplify the expression inside the parentheses:

2/11 - 3/8

To add or subtract fractions, we need a common denominator. The least common multiple of 11 and 8 is 88, so let's convert both fractions to have a denominator of 88:

(2/11) * (8/8) - (3/8) * (11/11) 16/88 - 33/88

Now, we can subtract the fractions:

(16 - 33)/88 -17/88

Now, let's substitute this value back into the original expression:

11/20 * (-17/88) + 11/20 * 3/8

To multiply fractions, we simply multiply the numerators together and the denominators together:

(-17/88) * (11/20) + (11/20) * (3/8) -187/1760 + 33/160

To add fractions, we need a common denominator. The least common multiple of 1760 and 160 is 1760, so let's convert both fractions to have a denominator of 1760:

(-187/1760) + (33/160) * (11/11) (-187/1760) + (363/1760)

Now, we can add the fractions:

(-187 + 363)/1760 176/1760

Finally, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 8:

176/1760 = (176/8) / (1760/8) = 22/220

The simplified result of the expression is 22/220.
