Answer 1

Answer:

48/90

Step-by-step explanation:

3/5 - 7/9 + 1/10 - 11/18

(3/5 + 1/10) - (7/9 - 11/18)

7/10 - 3/18

48/90

Answer 2

The value is $- \frac{31}{45}$

GIVEN:- 3/5 + (-7/9) + 1/10 + (-11/18)

TO FIND:- value

SOLUTION:-

• The sum of a positive number and a negative number is subtracted.

According to the question,

$\frac{3}{5} + ( - \frac{7}{9} ) + \frac{1}{10} + ( - \frac{11}{18} ) \\ = \frac{3}{5} - \frac{7}{9} + \frac{1}{10} - \frac{11}{18}$

By taking LCM of all the denominators we get 90

$= \frac{3 \times 18}{5 \times 18} - \frac{7 \times 10}{9 \times 10} + \frac{1 \times 9}{10 \times 9} - \frac{11 \times 5}{18 \times 5} \\ = \frac{54}{90} - \frac{70}{90} + \frac{9}{90} - \frac{55}{90} \\ = \frac{54 - 70 + 9 - 55}{90} \\ = \frac{63 - 125}{90} \\ = \frac{ - 62}{90} \\ = - \frac{31}{45}$

Hence, the value is $- \frac{31}{45}$
