Step by Step Solution
Step 1 :
5
Simplify ——
16
Equation at the end of step 1 :
5 5
((14 - ——) - 3) - ——
32 16
Step 2 :
5
Simplify ——
32
Equation at the end of step 2 :
5 5
((14 - ——) - 3) - ——
32 16
Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 32 as the denominator :
14 14 • 32
14 = —— = ———————
1 32
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:
14 • 32 - (5) 443
————————————— = ———
32 32
Equation at the end of step 3 :
443 5
(——— - 3) - ——
32 16
Step 4 :
Rewriting the whole as an Equivalent Fraction :
4.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 32 as the denominator :
3 3 • 32
3 = — = ——————
1 32
Adding fractions that have a common denominator :
4.2 Adding up the two equivalent fractions
443 - (3 • 32) 347
—————————————— = ———
32 32
Equation at the end of step 4 :
347 5
——— - ——
32 16
Step 5 :
Calculating the Least Common Multiple :
5.1 Find the Least Common Multiple
The left denominator is : 32
The right denominator is : 16
Prime Factor | Left Denominator | Right Denominator | L.C.M = Max {Left,Right} |
---|---|---|---|
2 | 5 | 4 | 5 |
Product of all Prime Factors | 32 | 16 | 32 |
Least Common Multiple:
32
Calculating Multipliers :
5.2 Calculate multipliers for the two fractions
Denote the Least Common Multiple by L.C.M
Denote the Left Multiplier by Left_M
Denote the Right Multiplier by Right_M
Denote the Left Deniminator by L_Deno
Denote the Right Multiplier by R_Deno
Left_M = L.C.M / L_Deno = 1
Right_M = L.C.M / R_Deno = 2
Making Equivalent Fractions :
5.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 347 —————————————————— = ——— L.C.M 32 R. Mult. • R. Num. 5 • 2 —————————————————— = ————— L.C.M 32
Adding fractions that have a common denominator :
5.4 Adding up the two equivalent fractions
347 - (5 • 2) 337
————————————— = ———
32 32
Final result :
337
——— = 10.53125
