The sum of the reciprocal of which four natural numbers is 1995 / 34
∵ 1995 = 3 × 5 × 7 × 19 and 3 + 5 + 7 + 19 = 34
The four numbers are: 1995 ／ 3; 1995 ／ 5; 1995 ／ 7; 1995 ／ 19
That is, the four numbers are 665; 399; 285; 105
The sum of the reciprocal of two consecutive natural numbers is 11 / 30. The sum of these two natural numbers is 11. Why? What is the formula?
5,6 1\5+1\6=11、30
The reciprocal sum of two adjacent natural numbers is 11 / 30. What are the two natural numbers?
11/30=(5+6)/30=1/5+1/6
The sum of the reciprocal of two adjacent natural numbers is 11 / 30, which are (5) and (6) respectively
The reciprocal sum of two consecutive natural numbers is 1130. These two numbers are______ And______ ．
Let one of the numbers be a, then the other number is a + 1. From the meaning of the question, we get that & nbsp; 1A + 1A + 1 = 1130, a + (a + 1) a × (a + 1) = 1130, so a + (a + 1) = 11, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 2A = 10, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp
