Multiplying by 1 does not change the ratio
Step-by-step explanation:
Multiplying a/b by c/c gives the equivalent ratio (ac)/(bc) because c/c is 1, the multiplicative identity element. Multiplying by 1 does not change the ratio.
Answer: 28 and 30
Step-by-step explanation:
Let the house numbers on the street be represented by n and n+2 sine they are consecutive even integers. Therefore,
n + (n + 2) = 58
2n + 2 = 58
2n = 58 - 2
2n = 56
n = 56/2
n = 28
Therefore the second number will be:
= n + 2
= 28 + 2
= 30
The numbers are 28 and 30
