Introduction

Fractions are an essential part of mathematics, and they can be used to represent a wide range of mathematical concepts. However, when fractions are combined using arithmetic operations such as addition, subtraction, multiplication, and division, they can become complex and challenging to solve. In this article, we will explore four different complex fractions and provide step-by-step solutions to each of them.

Complex Fraction (a): 15+13×12\frac{1}{5} + \frac{1}{3} \times \frac{1}{2}

To solve this complex fraction, we need to follow the order of operations (PEMDAS):

  1. Multiply 13\frac{1}{3} and 12\frac{1}{2}: 13×12=16\frac{1}{3} \times \frac{1}{2} = \frac{1}{6}
  2. Add 15\frac{1}{5} and 16\frac{1}{6}: 15+16=630+530=1130\frac{1}{5} + \frac{1}{6} = \frac{6}{30} + \frac{5}{30} = \frac{11}{30}

Therefore, the solution to complex fraction (a) is 1130\frac{11}{30}.

Complex Fraction (b): 2313÷12\frac{2}{3} - \frac{1}{3} \div \frac{1}{2}

To solve this complex fraction, we need to follow the order of operations (PEMDAS):

  1. Divide 13\frac{1}{3} by 12\frac{1}{2}: 13÷12=13×21=23\frac{1}{3} \div \frac{1}{2} = \frac{1}{3} \times \frac{2}{1} = \frac{2}{3}
  2. Subtract 23\frac{2}{3} from 23\frac{2}{3}: 2323=0\frac{2}{3} - \frac{2}{3} = 0

Therefore, the solution to complex fraction (b) is 00.

Complex Fraction (c): 43÷29+34\frac{4}{3} \div \frac{2}{9} + \frac{3}{4}

To solve this complex fraction, we need to follow the order of operations (PEMDAS):

  1. Divide 43\frac{4}{3} by 29\frac{2}{9}: 43÷29=43×92=366=6\frac{4}{3} \div \frac{2}{9} = \frac{4}{3} \times \frac{9}{2} = \frac{36}{6} = 6
  2. Add 66 and 34\frac{3}{4}: 6+34=244+34=2746 + \frac{3}{4} = \frac{24}{4} + \frac{3}{4} = \frac{27}{4}

Therefore, the solution to complex fraction (c) is 274\frac{27}{4}.

Complex Fraction (d): 35(2313)\frac{3}{5} - \left(\frac{2}{3} - \frac{1}{3}\right)

To solve this complex fraction, we need to follow the order of operations (PEMDAS):

  1. Subtract 13\frac{1}{3} from 23\frac{2}{3}: 2313=13\frac{2}{3} - \frac{1}{3} = \frac{1}{3}
  2. Subtract 13\frac{1}{3} from 35\frac{3}{5}: 3513=915515=415\frac{3}{5} - \frac{1}{3} = \frac{9}{15} - \frac{5}{15} = \frac{4}{15}

Therefore, the solution to complex fraction (d) is 415\frac{4}{15}.
