Question

subtract -5/7 from -7/11 then subtract -7/11 from -5/7 are they equal​

Answer 1

Answer:

No

Step-by-step explanation:

No, they are not equal.

$\frac{ - 7}{11} - \frac{ - 5}{7} \\ = \frac{ - 7}{11} + \frac{5}{7} \\ LCM \: of \: 11 \: and \: 7 \: is \: 77 \\ = \frac{ - 7 \times 7}{11 \times 7} + \frac{5 \times 11}{7 \times 11} \\ = \frac{ - 49}{77} + \frac{55}{77} \\ = \frac{6}{77}$

$\frac{ - 5}{7} - \frac{ - 7}{11} \\ = \frac{ - 5}{7} + \frac{7}{11} \\ LCM \: of \: 7 \: and \: 11 \: is \: 77 \\ = \frac{ - 5 \times 11}{7 \times 11} + \frac{7 \times 7}{11 \times 7} \\ = \frac{ - 55}{77} + \frac{49}{77} \\ = \frac{ - 6}{77}$

Hence they are equal
