Question

Read the temperatures shown to the nearest 0.5°C.

A thermometer showing degrees Fahrenheit on one side and degrees Celsius on the other side in increments of one degree. The top red line is just under 1 mark below 100 on the Fahrenheit scale and 3 marks below 40 on the Celsius scale.

°C
A thermometer showing degrees Celsius from 30 to 50 in 1 degree increments. The top of the red line is between the marks for 42 and 43.

°C

Answer 1

First thermometer: 37.0°C (three 1°C marks below 40°C → 37°C, to nearest 0.5°C = 37.0°C).

Second thermometer: 42.5°C (between 42 and 43°C → rounds to 42.5°C).
