is it easier to subtract when the numbers are written above and below each other? explain your answer
Cerrena [4.2K]
Usually its easier to subtract numbers written vertically because of the sheer fact that you're just taking away instead of adding on. If you have basic idea about adding then you should understand subtracting easier. But, because most schools teach adding first its easier for some.

K=5/9(F-32) + 273.15. Solve for F. If you have an answer please leave an explanion, but you Don't have to.
Sveta_85 [38]

K = \frac{5}{9}(F - 32) + 273.15

To cancel out the 5/9, you can either multiply everything by the denominator and divide it down, or multiply everything by the reciprocal of the fraction (\frac{9}{5}. Multiplying by the reciprocal is definitely easier if you can use a calculator:

\frac{9}{5}K = (F - 32) + 491.67

Subtract 491.67 from both sides:

\frac{9}{5}K - 491.67 = F - 32

Finish off by adding 32 to both sides:

\frac{9}{5}K - 459.67 = F

Therefore, F = \frac{9}{5}K - 459.67.

Hope this helps! :)
