Answer: No.
Step-by-step explanation: The left side, -0.7 doesn't equal the right side, -0.8, so it is false.
To find equivalent fractions, multiply the the numerator and denominator by the same whole number.
[tex]-\frac{7}{10}\times\frac{2}{2} =-\frac{14}{20}[/tex]
[tex]-\frac{7}{10}\times\frac{3}{3} =-\frac{21}{30}[/tex]
[tex]-\frac{7}{10}\times\frac{4}{4} =-\frac{28}{40}[/tex]
And so on...
[tex]-\frac{4}{5}\times\frac{2}{2} =-\frac{8}{10}[/tex]
[tex]-\frac{4}{5}\times\frac{3}{3} =-\frac{12}{18}[/tex]
[tex]-\frac{4}{5}\times\frac{4}{4} =-\frac{16}{20}[/tex]
And so on...
If we keep doing this, they won't equal each other.
So no, they're not equivalent.
