Answer:
Conversion a mixed number 2 1/6
to a improper fraction: 2 1/6 = 2 1/6
= 2 · 6 + 1/6
= 12 + 1/6
= 13/6
Multiply the whole number 2 by the denominator 6. Whole number 2 equally 2 * 6/6 = 12/6
To find new numerator: 13/6 - 2/3= 13/6 - 2 · 2/ 3 · 2 = 13/6- 4/6= 13 - 4/6= 9/6= 3 · 3/3 · 2= 3/2
Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13
Write a previous answer (new numerator 13) over the denominator 6.
Two and one sixth is thirteen sixths
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(6, 3) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 3 = 18. In the next intermediate step , cancel by a common factor of 3 gives 3/2
.
In words - thirteen sixths minus two thirds = three halfs.
I'm not sure if this is right but if it's not I did math for nothing-.
