Question

Какое из чисел 0,7 3/10 2/12 и 1/4 меньше 1/5?

Answer 1

Для того, чтобы сравнить эти дроби, нужно привести их к общему знаменателю.
7/10 и 1/5 = 7/10 и 2/10
3/10 и 1/5 = 3/10 и 2/10
2/12 и 1/5 = 10/60 и 12/60
1/4 и 1/5 = 5/20 и 4/20
Получается, что меньше 2/12

Answer 2

I can help you with math problems and other topics. To compare fractions, you need to find a common denominator and then compare the numerators. One way to do this is to multiply each fraction by the least common multiple of the denominators. In this case, the least common multiple of 10, 12, 4, and 5 is 60. So, we have:

$$0.7 = \frac{7}{10} \times \frac{6}{6} = \frac{42}{60}$$ $$\frac{3}{10} \times \frac{6}{6} = \frac{18}{60}$$ $$\frac{2}{12} \times \frac{5}{5} = \frac{10}{60}$$ $$\frac{1}{4} \times \frac{15}{15} = \frac{15}{60}$$ $$\frac{1}{5} \times \frac{12}{12} = \frac{12}{60}$$

Now, we can compare the numerators and see that the smallest one is 10, which corresponds to the fraction $$\frac{2}{12}$$. Therefore, the answer is $$\frac{2}{12}$$ is the smallest fraction among the given numbers. You can also use an online fraction calculator to check your answer. I hope this helps.
