Question

-16/9+-5/12+7/18 evaluate​

Answer 1

Step-by-step explanation:

take out (-) common

-( 16/9 - 5/12 - 7/18)

L.C.M (9,12,18) = 36

-( 16×36/9 - 5×36/12 - 7×36/18)

= -(64 - 15 - 14)

= - 35 Ans

Answer 2

Answer:

$=>- \frac{253}{144}$

Step-by-step explanation:

Given that:-

$\frac{-16}{9}+\frac{-5}{12}+\frac{7}{18}$

To simplify the expression we have to use the DMAS rule:

D - division ( ÷ )

M - multiplication ( × )

A - addition ( + )

S - subtraction ( - )

As we have,

$=> \frac{-16}{9}+\frac{-5}{12}+\frac{7}{18}$

Now, we have to find the LCM:

$=> \frac{-16\times 16}{9\times 16}+\frac{-5\times 12}{12\times 12}+\frac{7\times 9}{18\times 9}$

By further calculating it we get,

$=> \frac{-256}{144}+\frac{-60}{144}+\frac{63}{144}$

Combining the fractions, we get

$=> \frac{(-256+-60+63)}{144}$

$=> \frac{-253}{144}$
