Preliminary:
Fractions in Mathematics are rational numbers that can be written in the form x/y, where x and y are integers, and y 0 and the number x is not a multiple of y. In fractions x is called the numerator while y is called the denominator.
Fraction Types:
- Common Fraction = is a fraction expressed in the form x/y, x as the numerator and y as the denominator. x and y are integers and y 0
- Mixed fraction = is a combination of whole numbers and fractions, expressed in the form a [tex] \frac{b}{c} [/tex]
- Decimal fractions are indicated by a comma (,) as a separator between the round and fractional parts. The round part is in front of the comma and the fraction part is behind it. One digit after the comma means the denominator of the fraction 10, two digits after the comma means the denominator of the fraction 100, and so on.
- A percent fraction is a fraction that has a denominator of 100, expressed in the form a%. example 50% is the same as [tex] \frac{50}{100} [/tex]
Answer:
[tex] \frac{1}{2} [/tex]
Step-by-step explanation:
[tex]3( \frac{6}{8} - \frac{1}{2} ) + 0.25 = \frac{3 \times 2}{4 \times 2} - \frac{1}{2} = \frac{3 - 2 \times 1}{4} = \frac{1}{4} + 0.25 = \frac{50}{100} = \frac{1 \times 50}{2 \times 50} = \frac{1}{2} [/tex]
