Question

(3 4/5-2 3/10):1 1/2

Answer 1

$(3 \frac{4}{5} - 2 \frac{3}{10}) \div 1 \frac{1}{2} = (\frac{38}{10} - \frac{23}{10}) \times \frac{2}{3}$

$= \frac{15}{10} \times \frac{2}{3} = \frac{5}{5} \times \frac{1}{1} = 1$

Answer 2

To calculate the expression (3 4/5 - 2 3/10) ÷ 1 1/2, follow these steps:

Step 1: Convert mixed numbers to improper fractions. 3 4/5 can be written as an improper fraction: (3 * 5 + 4) / 5 = 19/5 2 3/10 can be written as an improper fraction: (2 * 10 + 3) / 10 = 23/10

Step 2: Subtract the two fractions. (19/5) - (23/10) = (38/10) - (23/10) = (38 - 23) / 10 = 15/10 = 3/2

Step 3: Divide the result by 1 1/2. To divide a fraction by a whole number, we multiply the fraction by the reciprocal of the whole number.

1 1/2 can be written as an improper fraction: (1 * 2 + 1) / 2 = 3/2

Now, the division is (3/2) ÷ (3/2).

To divide, multiply by the reciprocal: (3/2) * (2/3) = (3 * 2) / (2 * 3) = 6/6 = 1

So, the final result is 1.
