Question

the question is : ( 1 + 1/15 - 9/10 )
help me find the LCM of this and pease show me the steps

Answer 1

$= (1 + \frac{1}{15} - \frac{9}{10} )$

$= ( \frac{1}{1} + \frac{1}{15} - \frac{9}{10} )$

$= ( \frac{30 + 2 - 27}{30} )$

$= \frac{30 - 25}{30}$

$= \frac{5}{30}$

$= \frac{1}{6}$

Answer 2

$( \frac{1}{1} + \frac{1}{15} - \frac{9}{10} ) = \frac{1}{6}$

Step-by-step explanation:

$lcm \: of \: 1 \: .\: 15 \: .\: 10 = 30 \\ { \frac{(1 \times 30) + (1 \times 2) - (9 \times 3)}{30} } \\ \\ \\ = {\frac{30 + 2 - 27}{30} } \\ \\ = \frac{3 + 2}{30 } \\ \\ = \frac{5}{3 0} = \frac{1}{6}$
