Answer:
Explanation:
3/8 + 2/3 - 1/4 = 19/24 ≅ 0.7916667
Add: 3/
8
+ 2/
3
= 3 · 3/
8 · 3
+ 2 · 8/
3 · 8
= 9/
24
+ 16/
24
= 9 + 16/
24
= 25/
24
It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 3) = 24. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 3 = 24. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - three eighths plus two thirds is twenty-five twenty-fourths.
Subtract: the result of step No. 1 - 1/
4
= 25/

= 25/
24
- 1 · 6/
4 · 6
= 25/
24
- 6/
24
= 25 - 6/
24
= 19/

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(24, 4) = 24. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 24 × 4 = 96. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - twenty-five twenty-fourths minus one quarter is nineteen twenty-fourths.
