#### Answer

a. -11$\lt$-9
b. 4.511$\gt$4.151
c. $\frac{7}{8}$ $\gt$ $\frac{2}{3}$

#### Work Step by Step

Insert $\lt$, $\gt$ or = between the pairs of numbers to form true statements
a. -11 and -9
We know from the numberline that -11 is to the left of -9, this results in -11 being less than ($\lt$) -9: -11$\lt$-9
b. 4.511 and 4.151
We know from the numberline that 4.511 is to the right of 4.151, this results in 4.511 being greater than ($\gt$) 4.151:
4.511$\gt$4.151
c. $\frac{7}{8}$ and $\frac{2}{3}$
We know from the numberline that $\frac{7}{8}$ is greater than ($\gt$) $\frac{2}{3}$: $\frac{7}{8}$ $\gt$ $\frac{2}{3}$
