Question

-4/7 + 7/6 + 2/7
(step by step explanation needed)​

Answer 1

the lcm of 7,6,7 is 42

7 multiply 6 is 42

so, 6×(-4)= -24

6 multiply 7 is 42

so, 7×7=49

7 multiply 6 is 42

so, 6×2=12

Now we have,

$\frac{ - 24 + 49 + 12}{42} \: \: add \: the \: plus \: sign \: first \ \\ \\ \frac{ - 24 + 61 }{42} \\ \\ \frac{37 }{42}$
