If I am correct the answer is 1.
You can do multiply 3 by 6/8 which will give you 2 1/4 or if in a decimal 2.25.
Then do 3 by -1/2 which will give you -1 1/2 and in decimal its -1.5.
You continue with the equation, 2.25 -1.5 = 0.75 + 0.25 = 1
Add them all together and you get 1...!
Hope this Helps :)
First you need to make both denominators the same number.
The number we can use is 21.
6/7 : to make the denominator 21, you need to multiply the numerator and the denominator by 3.
6 × 3 = 18
7 × 3 = 21
The equivalent is 18/21
1/3 : to make the denominator 21, you need to multiply the numerator and the denominator by 7.
1 × 7 = 7
3 × 7 = 21
The equivalent is 7/21
18/21 + 7/21 = 25/21 = 1 4/21
