Solving the Expression 6/7 ÷ 3/5 * 1 2/5

To solve the given expression, we can follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, let's convert the mixed number 1 2/5 to an improper fraction: 1 2/5 = (5*1 + 2)/5 = 7/5

Now, we can proceed with solving the expression step by step:

1. Division (6/7 ÷ 3/5): - To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction. - (6/7) ÷ (3/5) = (6/7) * (5/3) = (6*5)/(7*3) = 30/21 = 10/7

2. Multiplication (10/7 * 7/5): - Multiply the fractions together. - (10/7) * (7/5) = (10*7)/(7*5) = 70/35 = 2

3. Addition (2 + 7/5): - Convert the whole number 2 to a fraction with the same denominator as 7/5. - 2 = 2*5/5 = 10/5 - Now, add the fractions: 10/5 + 7/5 = 17/5

Final Answer:

The value of the expression 6/7 ÷ 3/5 * 1 2/5 is 17/5 or 3 2/5.
