Help me with a 7th grade math problem?

Question

11/14 - (-16/21)

I know how to do this problem and all the steps but when i constructed it i keep on getting it wrong!

Answer 1

First you need to change the denominators so they're the same:

(11/14) * (3/3) = 33/42
(-16/21) * (2/2) = -32/42

Therefore,

33/42 - (-32/42) = 33/42 + 32/42
= 65/42
= 1 23/42

Answer 2

Step 1: 11/14+16/21 Minus a negative makes a positive
Step 2: 11/14(3)+16/21(2) Multiply to get same denominators
Step 3: 33/42 +32/42
Step 4: 65/42 Add them together

DONE

Answer 3

When you see two negative signs like this, change it to + + because subtracting a negative is the same as adding a positive.
So 11/14 + (+ 16/21) = 33/42 + 32/42 = 65/42 or 1 and 23/42

Answer 4

11/14 - (-16/21) = 11/14 + 16/21
= 33/42 + 33/42
= 65/42
= 1 23/42

Answer 5

11/14 - (-16/21)
= 11/14 + 16/21
=33/42 + 32/42
=65/42
=1 23/42

Answer 6

first, find a common denominater, which would be 42 in this case

put both fractions into that common denominator by multiplying both the top and the bottom by the factor
(3/3)(11/14) - (2/2)(-16/21)
=(33/42) - (-32/42)
=(33/42) + (32/42)
add the numerators gives
=65/42

Answer 7

11/14 - (-16/21)=
11/14+16/21= <== two - cancels out so = +
1 23/42 <== added!

Answer 8

11/14 - (-16/21)
33/42-(-32/42)
65/42

Answer 9

-- = +
so rewriting with common denominator:
11/(7x2) + 16/(7x3) = 11(3)/(7x2x3) + 16(2)/(7x3x2)
= (33+16)/42 = 49/42 = (7x7)/(7x6) = 7/6

Answer 10

First, 11/14=231/294 -16/21=-224/294

-224/294 - 231/294= -7/294!

-7/294

I hope I could help!
