QUESTION
1/60-1/42+1/90

Please tell the explanation ​

Answer 1

Answer:

$\large{ \fbox{ \pink{❥Q}}{ \fbox{ \purple{U}}{ \fbox{ \blue{E}}{ \fbox{ \red{S}}{ \fbox{ \orange{T}}{ \fbox{ \green{I}}{ \fbox{ \pink{O}}{ \fbox{ \purple{N}}}}}}}}}}$

Solve :

$\frac{1}{60} - \frac{1}{42} + \frac{1}{90}$

$\large{ \fbox{ \pink{❥A}}{ \fbox{ \purple{N}}{ \fbox{ \blue{S}}{ \fbox{ \red{W}}{ \fbox{ \orange{E}}{ \fbox{ \green{R}}}}}}}}$

$\large \mathfrak{ \underline{ \underline{ \pink{Solⁿ :}}}}$

At first, we have to find the LCM of denominators.

LCM of denominators ( 60, 42, 90)

$= 1260$

Now,

$= > \frac{1}{60} - \frac{1}{42} + \frac{1}{90} = \frac{21 - 30 + 14}{1260}$

$= \frac{ \cancel{5}}{ \cancel{1260}} = \frac{1}{252}$

$\huge{\frac{1}{252}✅ }$

Hope it helps...
