Question

Find the value of x if the numbers in a set are in proportion
a) 2,3,4
b) 5, 10, 3,x​

Answer 1

Step-by-step explanation:

b)given , 5,10,3,x are in proportion

here, extremes are 5,x

and means are 10,3

we know ,since they are in proportion,

product of extremes= product of means

so, 5×x=10×3

or,

5x=30

or,

x=30/5= 6

hence ,the value of x is 6
