Question

what is the fourth proportional of 0.006,1.2&6/25?​

Answer 1

Answer:

4

Step-by-step explanation:

let the fourth proportinal be x

therefore,

0.0006/1.2=6/25/x

60/12000*25/6= 1/x

1/4= 1/x

there fore

x= 4

Answer 2

Step-by-step explanation:

Given quantities are 0.006;1.2;6/25

Let the fourth proportional be X

then,

0.006:1.2::6/25:X

Product of extremes= 0.006×X=0.006X

Product of means =1.2×6/25

=7.2/25

= 72/250

=0.288

Since they are in proportion then

Product of extremes =Product of means

=>0.006X=0.288

=>X=0.288/0.006

=>X=(288/1000)/(6/1000)

=>X=288/6

=>X=48

The fourth proportional is 48
