Answer 1

Ответ:

A)269/13

Б)4412/45

В)1901/53

Г)2799/62

Answer 2

Let's solve each of these expressions step by step:

A) 21 - 4/13

To subtract fractions, we need a common denominator. In this case, the denominator is 13. So, we convert 21 into a fraction with a denominator of 13:

21 = (21 * 13) / 13 = 273/13

Now we can subtract the fractions:

273/13 - 4/13 = (273 - 4) / 13 = 269/13

Therefore, A) 21 - 4/13 is equal to 269/13.

B) 99 - 43/45

Again, we need a common denominator to subtract fractions. In this case, the denominator is 45. Converting 99 into a fraction with a denominator of 45:

99 = (99 * 45) / 45 = 4455/45

Now we can subtract the fractions:

4455/45 - 43/45 = (4455 - 43) / 45 = 4412/45

Therefore, B) 99 - 43/45 is equal to 4412/45.

C) 36 - 7/53

To subtract fractions, we need a common denominator. In this case, the denominator is 53. So, we convert 36 into a fraction with a denominator of 53:

36 = (36 * 53) / 53 = 1908/53

Now we can subtract the fractions:

1908/53 - 7/53 = (1908 - 7) / 53 = 1901/53

Therefore, C) 36 - 7/53 is equal to 1901/53.

D) 46 - 53/62

To subtract fractions, we need a common denominator. In this case, the denominator is 62. Converting 46 into a fraction with a denominator of 62:

46 = (46 * 62) / 62 = 2852/62

Now we can subtract the fractions:

2852/62 - 53/62 = (2852 - 53) / 62 = 2799/62

Therefore, D) 46 - 53/62 is equal to 2799/62.

To summarize: A) 21 - 4/13 = 269/13 B) 99 - 43/45 = 4412/45 C) 36 - 7/53 = 1901/53 D) 46 - 53/62 = 2799/62
