If a, b and c are numbers such that a:b:c = 2:3:5 and b= 30 then, find the sum of a+b+c ?​

100

Step-by-step explanation:

2:3:5

20:30:50

20 + 30 + 50 = 50 + 50 = 100

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
