Answer:
[tex]2\frac{3}{4}^{\circ}C[/tex]
Step-by-step explanation:
Given,
The temperature on Saturday = [tex]6\frac{1}{2}^{\circ}C=\frac{13}{2}^{\circ}C[/tex]
Also, on Sunday, it became [tex]3\frac{3}{4}^{\circ}C[/tex] colder,
So, the temperature on Sunday = The temperature on Saturday - [tex]3\frac{3}{4}^{\circ}C[/tex]
[tex]=\frac{13}{2}-\frac{15}{4}[/tex]
[tex]=\frac{26-15}{4}[/tex]
[tex]=\frac{11}{4}[/tex]
[tex]=2\frac{3}{4}^{\circ}C[/tex]
