Question

26${}^{\circ }$C above 0${}^{\circ }$C temperature and 13${}^{\circ }$C below 0${}^{\circ }$C temperature can be represented on the number line as-

• A. -26${}^{\circ }$C and +13${}^{\circ }$C
• B. +26${}^{\circ }$C and -13${}^{\circ }$C
• C. -26${}^{\circ }$C and -13${}^{\circ }$C
• D. +26${}^{\circ }$C and +13${}^{\circ }$C

Answer 1

The correct option is B

+26${}^{\circ }$C and -13${}^{\circ }$C

On the number line, the temperature above 0°C is taken as positive and below 0° is taken as negative.
Since 26 is above 0° C it is represented as + 26°C.
13 is below 0°C , it is represented as -13°C.
