Find the sum or difference. all answers should be in simplest form 1 /3/7 + 10 6/7

12 1/9 + 10 2/3

3 5/9 + 1 3/9

5 2/3 - 4 5/9

1. 12 2/7

2. 22 7/9

3. 4 8/9

4. 1 1/9

Step-by-step explanation:

1. 1 3/7+10 6/7

Change to improper fractions and solve

(10/7)+(76/7)=(10+76)/7=86/7

Convert 86/7 to mixed number

12 2/7

2. 12 1/9+10 2/3

Change to improper fractions and solve

(109/9)+(32/3)=(109+96)/9=205/9

Convert 205/9 to mixed number

22 7/9

3. 3 5/9 + 1 3/9

Change to improper fractions and solve

(32/9)+(12/9)=(32+12)/9=44/9

Convert 44/9 to mixed number

4 8/9

4. 5 2/3-4 5/9

Change to improper fractions and solve

(17/3)-(41/9)=(51-41)/9=10/9

Convert 10/9 to mixed number

1 1/9

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
