4. determine two numbers with a ratio of 2:5, if one number is 15 more than the other.​

Sagot :

Step-by-step explanation:

x is the smaller nr

15 + x is the larger nr

x / (15 + x) = 2 / 5

5x = 2(15 + x)

5x = 30 + 2x

5x - 2x = 30

3x = 30

x = 10 the smaller nr

15 + x = 25 the larger nr

to check

10/25 = 2/5
