Answer 3

Перевод обыкновенных дробей в десятичную форму:

1) 3/4: To convert the fraction 3/4 into a decimal, divide the numerator (3) by the denominator (4): 3 ÷ 4 = 0.75

2) 2 1/5: To convert the mixed fraction 2 1/5 into a decimal, first convert the mixed fraction into an improper fraction: 2 1/5 = (2 * 5 + 1) / 5 = 11/5 Then, divide the numerator (11) by the denominator (5): 11 ÷ 5 = 2.2

3) 1 5/86: To convert the mixed fraction 1 5/86 into a decimal, first convert the mixed fraction into an improper fraction: 1 5/86 = (1 * 86 + 5) / 86 = 91/86 Then, divide the numerator (91) by the denominator (86): 91 ÷ 86 ≈ 1.0581

So, the decimal equivalents of the given fractions are: 1) 3/4 = 0.75 2) 2 1/5 = 2.2 3) 1 5/86 ≈ 1.0581
