Math Problem Statement

Find the value of the expression: (2/5 + 2/3) / (3/3 + 1/2 + 2/5) + 1/3

Solution

Let's break down and solve the given mathematical expression from the image.

The expression provided is:

25+2333+12+25+13\frac{\frac{2}{5} + \frac{2}{3}}{\frac{3}{3} + \frac{1}{2} + \frac{2}{5}} + \frac{1}{3}

Step 1: Simplify the numerator

The numerator of the fraction is:

25+23\frac{2}{5} + \frac{2}{3}

To add these two fractions, we need a common denominator. The least common denominator (LCD) of 5 and 3 is 15. Convert each fraction:

25=615,23=1015\frac{2}{5} = \frac{6}{15}, \quad \frac{2}{3} = \frac{10}{15}

Now, add the fractions:

615+1015=1615\frac{6}{15} + \frac{10}{15} = \frac{16}{15}

Step 2: Simplify the denominator

The denominator of the fraction is:

33+12+25\frac{3}{3} + \frac{1}{2} + \frac{2}{5}

We know that 33=1\frac{3}{3} = 1. So the expression becomes:

1+12+251 + \frac{1}{2} + \frac{2}{5}

Now, find the LCD of 2 and 5, which is 10. Convert the fractions:

12=510,25=410\frac{1}{2} = \frac{5}{10}, \quad \frac{2}{5} = \frac{4}{10}

Now, add them:

1+510+410=1+910=19101 + \frac{5}{10} + \frac{4}{10} = 1 + \frac{9}{10} = \frac{19}{10}

Step 3: Combine the simplified numerator and denominator

Now we have:

16151910\frac{\frac{16}{15}}{\frac{19}{10}}

To divide fractions, multiply by the reciprocal of the denominator:

1615×1019=160285\frac{16}{15} \times \frac{10}{19} = \frac{160}{285}

Simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 5:

160÷5285÷5=3257\frac{160 \div 5}{285 \div 5} = \frac{32}{57}

Step 4: Add 13\frac{1}{3}

Now we need to add 3257+13\frac{32}{57} + \frac{1}{3}. To do this, find the LCD of 57 and 3, which is 57. Convert the fractions:

13=1957\frac{1}{3} = \frac{19}{57}

Now, add the fractions:

3257+1957=5157\frac{32}{57} + \frac{19}{57} = \frac{51}{57}

Simplify the fraction:

5157=51÷357÷3=1719\frac{51}{57} = \frac{51 \div 3}{57 \div 3} = \frac{17}{19}

Final Answer:

The value of the expression is 1719\frac{17}{19}.

However, none of the provided options match 1719\frac{17}{19}. It seems the options might not have the correct answer listed.
