Question

evaluate the following -12/-5 + 7/-3 + _5/14 + 22/7​

Answer 1

Answer:

256/70

Step-by-step explanation:

-12/-5 + 7/-3 + 5/14 + 22/7 {[-12/-5] minus will cut minus}

12/5 + 7/-3 - 5/14 - 22/7 {Taking LCM of 5,3,14,7}

(504 + (-490) +75 + 682)/210 {-490 bcoz -3's (-) will be transferred to 7}

(1261 - 490)/210 {Adding all positive integers}

771/210 = 257/70 {Diving 771 and 210 from 3}

Answer 2

$answer$

$step \: by \: step \: explanation$

$take \: lcm \: of \: - 5. \: - 3. \: 14 \: .7 \: which \: is \: 210$

$\frac{ - 12}{ - 5} = \frac{ - 504}{ - 210}$

$\frac{7}{ - 3} = \frac{490}{ - 210}$

$\frac{ - 5}{14} = \frac{ - 75}{210}$

$\frac{22}{7} = \frac{660}{210}$

$after \: that$

$\frac{ - 504 \times - 1}{ - 210 \times - 1 } = \frac{504}{210}$

$\frac{490}{ - 210} = \frac{490 \times - 1}{ - 210 \times - 1} = \frac{ - 490}{210}$

$after \: that$

$\frac{504 + - 490 + - 75 + 660}{210}$

$= \frac{599}{210}$
