Question

(4-2 1/2×3/5)÷3 1/3-1/3=?​

Answer 1

$(4 - 2 \frac{1}{2} \times \frac{3}{5} ) \div 3 \frac{1}{3} - \frac{1}{3} = (4 - \frac{5 \times 3}{2 \times 5} ) \div \frac{10}{3} - \frac{1}{3} = (4 - 1 \frac{1}{2} ) \div \frac{10}{3} - \frac{1}{3} = \frac{5}{2} \div \frac{10}{3} - \frac{1}{3} = \frac{5 \times 3}{2 \times 10} - \frac{1}{3} = \frac{3}{4} - \frac{1}{3} = \frac{9}{12} - \frac{4}{12} = \frac{5}{12}$

Answer 2

To solve the expression (4 - 2 1/2 × 3/5) ÷ (3 1/3 - 1/3), let's break it down step by step:

First, we'll simplify the expression within the parentheses: 2 1/2 is the same as 5/2, so the expression becomes: (4 - 5/2 × 3/5)

Next, we'll perform the multiplication: (4 - (5/2) × (3/5)) = (4 - 15/10) = (4 - 3/2)

Now, we'll simplify the expression within the second set of parentheses: 3 1/3 is the same as 10/3, so the expression becomes: (4 - 3/2) ÷ (10/3 - 1/3)

Next, we'll perform the subtraction: (4 - 3/2) ÷ (10/3 - 1/3) = (4 - 3/2) ÷ (9/3) = (4 - 3/2) ÷ 3

Finally, we'll perform the division: (4 - 3/2) ÷ 3 = (8/2 - 3/2) ÷ 3 = (5/2) ÷ 3 = 5/2 × 1/3 = 5/6

Therefore, (4 - 2 1/2 × 3/5) ÷ (3 1/3 - 1/3) equals 5/6.
