Question

The temperature is raised by 45/14 C from (-4/7)C . What would be the new temperature

Answer 1

Answer:

37/14

Step-by-step explanation:

after temperature - (-4/7)C

correct temperature - (-4/7+45/14)

lcm of 7 is 14

-4/7 is equal to -8/14

-8+45/14

37/14

Answer 2

Given:

The old temperature = -4/7 °C

The rise in temperature by °C = 45/14 °C

To find:

The new temperature after the rise in temperature=?

Solution:

• The new temperature can be found from the following steps:
• By adding the rise in temperature from the old temperature we will get the new temperature.

=> New temperature = $\frac{-4}{7}$ °C + $\frac{45}{14}$ °C

=> The Least Common Factor or the LCM of 7 and 14 is 14.

=> Therefore we need to make both the denominators 14.

=> New temperature = $\frac{-4 * 2}{7 * 2}$ + $\frac{45 * 1}{14 * 1}$

=> New temperature = $\frac{-8 + 45}{14}$

=> New temperature = $\frac{37}{14}$ °C

Hence, the new temperature is  $\frac{37}{14}$°C or 2.64 °C after rising in temperature.
