Question

The temperature on Saturday was 6 1/2°C. On Sunday, it became 3 3/4 °C colder. What was the temperature on Sunday?

Answer 1

6 1/2 - 3 3/4 =
13/2 - 15/4 =
26/4 - 15/4 =
11/4 =
2 3/4 degrees (or 2.75) <==

Answer 2

`2(3)/(4)^(\circ)C`

Explanation:

Given,

The temperature on Saturday =
`6(1)/(2)^(\circ)C=(13)/(2)^(\circ)C`

Also, on Sunday, it became
`3(3)/(4)^(\circ)C` colder,

So, the temperature on Sunday = The temperature on Saturday -
`3(3)/(4)^(\circ)C`

`=(13)/(2)-(15)/(4)`

`=(26-15)/(4)`

`=(11)/(4)`

`=2(3)/(4)^(\circ)C`
