For numbers 1 and 2; addition and subtraction of fraction
1. For addition of fraction with the same value of denominator, simply add the numerators; 1/8 + 3/8 + 4/8 will become (1+3+4)/8 or simply 8/8 = 1. The denominator or a divisor is the number below the line of the fraction, and the numerator is the number above the line.
2. In subtracting two fractions with different denominator, determine the least common multiple of the denominator, in the question, the equation is 8/9 - 1/2. The denominators are 9 and 2, to find its multiple, for one denominator is odd, just simply multiply the two numbers, thus giving a factor of 18. Next step is to divide 18 to the first denominator, which is 9, then multiply the resulting quotient to its numerator, giving a result of 16. Do the same for the second denominator, giving 9. Now you can subtract them, 16-9=7, the 7 is the numerator of the final answer, and 18 as its new denominator, thus the final answer is 7/18.
For 3-5. Just simply perform the operation, add or subtract the numbers with their place values, arrange them carefully do avoid confusion.
