A. Addition and subtraction involving eighths
Fractional arithmetic involves performing mathematical operations with fractions. Understanding how to add and subtract fractions is important when working with fractional equivalents.
When adding or subtracting fractions with eighths, it is necessary to ensure that the denominators are the same. Since the fraction 1/4 is equivalent to 2/8 (as shown in ), it can be added or subtracted directly with other fractions with denominators of eighths.
For example, if we want to add 1/4 to 3/8, we can combine the numerators and keep the denominator the same: 1/4 + 3/8 = (1 + 3) / 8 = 4/8.
However, it is important to note that fractions should be simplified to their simplest form after performing arithmetic operations. In this case, 4/8 can be simplified by dividing both the numerator and denominator by their greatest common factor (GCF), which is 4. So, 4/8 simplifies to 1/2.
Similarly, for subtraction involving eighths, we subtract the numerators while keeping the denominators the same. For example, if we want to subtract 3/8 from 1/2, we have: 1/2 – 3/8 = (1 – 3) / 8 = -2/8. Again, simplifying this fraction by dividing both the numerator and denominator by their GCF (which is 2), we get -1/4 as the simplified result.
B. Multiplication and division involving eighths
Multiplication and division with eighths are also important aspects of fractional arithmetic. When multiplying fractions with eighths, it is necessary to multiply the numerators together and multiply the denominators together. For example, if we want to multiply 1/4 by 3/8, we have: (1/4) * (3/8) = (1 * 3) / (4 * 8) = 3/32.
When dividing fractions with eighths, the reciprocal (or flipped fraction) of the divisor is multiplied by the dividend. For example, if we want to divide 1/4 by 3/8, we can multiply 1/4 by the reciprocal of 3/8, which is 8/3: (1/4) ÷ (3/8) = (1/4) * (8/3) = (1 * 8) / (4 * 3) = 8/12.
It is important to simplify the results obtained through multiplication and division in order to express them in their simplest form.
Understanding how to perform arithmetic operations with eighths and other fractions is crucial for solving math problems and real-world scenarios that involve fractional equivalents. It allows for accurate calculations and a better grasp of numerical relationships within fractions.
