Question

Математика 5 кл выполни деления3/28разд6/7

Answer 1

Чтобы разделить одну дробь на другую, нужно делимое умножить на дробь обратную делителю. Чтобы получилась обратная дробь числитель и знаменатель поменяем местами.

$\displaystyle\frac{3}{28} :\frac{6}{7} =\frac{3}{28} \cdot \frac{7}{6} =\frac{3\cdot7}{7\cdot4\cdot3\cdot2} =\frac{1}{4\cdot2}=\frac{1}{8} .$

Answer 2

Division in Mathematics

To solve the division problem 3/28 ÷ 6/7 in mathematics, you can use the following steps:

1. Convert the division to multiplication: To divide by a fraction, you can multiply by its reciprocal. So, the division problem becomes 3/28 × 7/6.

2. Multiply the numerators and denominators: Multiply the numerators (top numbers) together and the denominators (bottom numbers) together. In this case, it would be 3 × 7 = 21 for the numerator and 28 × 6 = 168 for the denominator.

3. Simplify the fraction (if necessary): If possible, simplify the fraction by finding the greatest common divisor of the numerator and denominator and dividing both by it. In this case, the fraction 21/168 can be simplified by dividing both the numerator and denominator by 3, resulting in 7/56.

So, the result of 3/28 ÷ 6/7 is 7/56.
