Question

Здравствуйте! Помогите пожалуйста сравнить дроби и объясните как это делать:а)3/10 и 0,21б)99/100 и 0,99в)7/10 и 0,08г)9/10 и 0,95Заранее огромное спасибо!

Answer 1

Сначала надо привести дроби к общему знаменателю. для этого надо найти число, которое будет делиться и на тот, и на этот знаменатель:
а) 30/100 и 21/100
затем надо сравнить числители:
а)30/100>21/100
теперь можно сделать аывод:
а)3/10>0,21

Answer 2

Comparing Fractions and Decimals

When comparing fractions and decimals, it's important to understand that fractions represent parts of a whole, while decimals represent a number on a number line. To compare fractions and decimals, we can convert the fractions to decimals or decimals to fractions, and then compare them.

Let's compare the given fractions and decimals:

a) 3/10 and 0.21:

To compare 3/10 and 0.21, we can convert the fraction 3/10 to a decimal. To do this, we divide the numerator (3) by the denominator (10):

3 ÷ 10 = 0.3

Now we can compare 0.3 and 0.21. Since 0.3 is greater than 0.21, we can say that 3/10 is greater than 0.21.

b) 99/100 and 0.99:

To compare 99/100 and 0.99, we can convert the fraction 99/100 to a decimal:

99 ÷ 100 = 0.99

Now we can compare 0.99 and 0.99. Since they are equal, we can say that 99/100 is equal to 0.99.

c) 7/10 and 0.08:

To compare 7/10 and 0.08, we can convert the fraction 7/10 to a decimal:

7 ÷ 10 = 0.7

Now we can compare 0.7 and 0.08. Since 0.7 is greater than 0.08, we can say that 7/10 is greater than 0.08.

d) 9/10 and 0.95:

To compare 9/10 and 0.95, we can convert the fraction 9/10 to a decimal:

9 ÷ 10 = 0.9

Now we can compare 0.9 and 0.95. Since 0.95 is greater than 0.9, we can say that 9/10 is less than 0.95.

In summary:

a) 3/10 > 0.21 b) 99/100 = 0.99 c) 7/10 > 0.08 d) 9/10 < 0.95

I hope this helps! Let me know if you have any further questions.
