Answer 2

Answer:

Third term =4

Step-by-step explanation:

let the third term of a proportion be x

then the terms of the proportion are 19,95,x and 20

a/b::c/d

so,

by using cross multiplication a×d=(::) b×c

• 19×20 = 95×X

• 380 = 95×X

• 380÷95=X

• 4 = X

Hence, third term = 4

terms of the proportion are: 19,95,4 and 20
