Answer:
13
—— = 4.33333
3
Explanation:
Step 1 :
1
Simplify —
3
Equation at the end of step 1 :
7 2 1
—+((3•(—-—))•2)
3 3 3
Step 2 :
2
Simplify —
3
Equation at the end of step 2 :
7 2 1
— + ((3 • (— - —)) • 2)
3 3 3
Step 3 :
Adding fractions which have a common denominator :
3.1 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:
2 - (1) 1
——————— = —
3 3
Equation at the end of step 3 :
7 1
— + ((3 • —) • 2)
3 3
Step 4 :
7
Simplify —
3
Equation at the end of step 4 :
7
— + 2
3
Step 5 :
Rewriting the whole as an Equivalent Fraction :
5.1 Adding a whole to a fraction
Rewrite the whole as a fraction using 3 as the denominator :
2 2 • 3
2 = — = —————
1 3
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 :
5.2 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:
7 + 2 • 3 13
————————— = ——
3 3
