Reformatting the input :

Changes made to your input should not affect the solution:

(1): "3.1" was replaced by "(31/10)". 2 more similar replacement(s)

Step by step solution :

Step 1 :

31

Simplify ——

10

Equation at the end of step 1 :

67 31

(((7h+(0-(——•d)))-13)+4d)-(——•h)

10 10

Step 2 :

67

Simplify ——

10

Equation at the end of step 2 :

67 31h

(((7h+(0-(——•d)))-13)+4d)-———

10 10

Step 3 :

Rewriting the whole as an Equivalent Fraction :

3.1 Adding a fraction to a whole

Rewrite the whole as a fraction using 10 as the denominator :

7h 7h • 10

7h = —— = ———————

1 10

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

7h • 10 + -67d 70h - 67d

—————————————— = —————————

10 10

Equation at the end of step 3 :

(70h - 67d) 31h

((——————————— - 13) + 4d) - ———

10 10

Step 4 :

Rewriting the whole as an Equivalent Fraction :

4.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 10 as the denominator :

13 13 • 10

13 = —— = ———————

1 10

Adding fractions that have a common denominator :

4.2 Adding up the two equivalent fractions

(70h-67d) - (13 • 10) 70h - 67d - 130

————————————————————— = ———————————————

10 10

Equation at the end of step 4 :

(70h - 67d - 130) 31h

(————————————————— + 4d) - ———

10 10

Step 5 :

Rewriting the whole as an Equivalent Fraction :

5.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 10 as the denominator :

4d 4d • 10

4d = —— = ———————

1 10

Adding fractions that have a common denominator :

5.2 Adding up the two equivalent fractions

(70h-67d-130) + 4d • 10 70h - 27d - 130

——————————————————————— = ———————————————

10 10

Equation at the end of step 5 :

(70h - 27d - 130) 31h

————————————————— - ———

10 10

Step 6 :

Adding fractions which have a common denominator :

6.1 Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(70h-27d-130) - (31h) 39h - 27d - 130

————————————————————— = ———————————————

10 10

Final result :

39h - 27d - 130

———————————————
