Question

Сравнить числа A)5_13 И 7_13 Б) 11_15 И 8_15 B)1 и 7_6 Г) 8_9 и 5_4.Обьсяните как вы решали

Answer 1

А) 5/13 и 7/13
так как у нас общий знаменатель, сравниваем числители
5 и 7
5<7
значит 5/13<7/13
б) 11/15 и 8/15
11>8
11/15>8/15
в) 1 и 7/6
1 можно представить как 6/6
привели к общему знаменателю 6, значит можем сравнить чистители
6<7
6/6<7/6
1<7/6
г) 8/9 и 5/4
приведем к общему знаменателю 36
первую дробь домножим на 4, вторую на 9
32/36 и 40/36
привели к общему знаменателю, значит можем сравнить числители
32<40
32/36<40/36
8/9<5/4

Answer 2

A) 5/13 and 7/13 To compare these fractions, we can look at the denominator first. Since the denominators are the same, we can compare the numerators directly. In this case, 7/13 is greater than 5/13.

B) 11/15 and 8/15 Again, the denominators are the same, so we can compare the numerators directly. 11/15 is greater than 8/15.

C) 1 and 7/6 To compare these numbers, we can convert 1 to a fraction with the same denominator as 7/6. In this case, the common denominator is 6. So 1 can be written as 6/6, and then we can compare 6/6 and 7/6. 7/6 is greater than 6/6.

D) 8/9 and 5/4 To compare these fractions, we need to find a common denominator. In this case, the common denominator is 36. We can convert 8/9 to 32/36 and 5/4 to 45/36. 45/36 is greater than 32/36.

So, in summary, we compared the fractions and numbers by either comparing the numerators directly when the denominators were the same, or by converting the numbers to have a common denominator and then comparing them.
