Question

18/7 - 1/4 + -16/21 + (-19/28)
please give me answer step by step I am so trying but it is impossible ,So please ​

Answer 1

Step-by-step explanation:

Hope you Understand..

Answer 2

so the place where there is -16/21 theres a + preceding it. so it'll turn into a minus.

and the place where there's-19/28 within ( ) , theres a + sign preceding it.and ( ) means multiply. now + × - = -

so in the 1st step you can see all the pluses turns into minuses.

then find the LCM of all the denominators because they all have plus / minus signs connecting each term.

so LCM of 7, 4, 21 and 28 is 84.

then toy want to arrange positives on the left side and negatives on right , which is already done in the sum.

now simply subtract the way you do it.

i dont know how good you understand math but, the reasons why I wrote 216-(21+64+57) is because 216-22-64-57 is the same. instead of subtracting each number one by one from 216, I directly added all the negative numbers and subtracted from the positive one. simple.

in the last step, I've reduced the fraction to the lowest form (although I would suggest that you check where it can be reduced any lower; I don't study math formally anymore. it's been ages. but I was good at it and it requires logic. that's it.)

I wish you all the best! if you dont understand such simplifications, feel free to ask me, I will be glad to help you when I can.

(please mark me the brainliest! I would really appreciate it!!!)
