Question

addition -12/3+23/4+-6/12​

Answer 1

Answer:

down below

Step-by-step explanation:

$\frac{-12}{3} + \frac{23}{4} + \frac{-6}{12}$

now take lcm

lcm= 12

=$\frac{-12}{3} =\frac{-12}{3} *\frac{4}{4} = \frac{-48}{12}$

=$\frac{23}{4} =\frac{23}{4} *\frac{3}{3} = \frac{69}{12}$

=$\frac{-6}{12} =\frac{-6}{12}$

now add

$\frac{-48}{12} + \frac{69}{12} + \frac{-6}{12}$ = $\frac{15}{12}$

answer is 15/12

hope this helps you!

Answer 2

To find : sum of rational numbers $\frac{-12}{3} + \frac{23}{4} + \frac{-6}{12}$

Solution:

•   To find the sum of given rational numbers we get need to equalize denominators of both the rational numbers. By taking LCM

• Therefore, LCM = 12

• Now, multiplying numerators of both rational numbers by same number as multiplied by denominators to make LCM.

• Therefore, we get, $\frac{-12}{3}+\frac{23}{4} + \frac{-6}{12} =\frac{-12\times 4 }{12}+\frac{23 \times 3}{12} + \frac{-6 \times 1}{12}$

                                                                 $= \frac{-48 + 69 - 6}{12}\\= \frac{15}{12}$

• On dividing we get $1.25$

Hence, sum of $\frac{-12}{3} + \frac{23}{4} + \frac{-6}{12}$ is $\frac{15}{12}$ or $1.25$ .
