Dominic: [tex] 2\frac{3}{4} [/tex]
Rachel : [tex]1 \frac{1}{3} [/tex] as long
How long Rachel worked:
[tex] 2\frac{3}{4} = \frac{11}{4} [/tex]
[tex]1 \frac{1}{3} [/tex] = [tex] \frac{4}{3} [/tex]
[tex] \frac{11}{4} [/tex] × [tex] \frac{4}{3} [/tex]
[tex] \frac{44}{12} [/tex] = [tex]3 \frac{2}{3} [/tex]
The answer is C. [tex] 3\frac{2}{3} [/tex]
