Question

In proportion, the first,second and fourth term are 5 ,8 and 16 respectively. find the third term​

Answer 1

Answer:

10

Step-by-step explanation:

If a : b = c : d are in proportion

then a/b = c/d

ad = bc

This is called cross product rule

Product of extremes = Product of means

5 : 8 : x : 16

8x = 80

x = 10

the third term is 10

Answer 2

Step-by-step explanation:

If a : b = c : d are in proportion then a/b = c/d

i.e ad = bc

Product of extremes = Product of means

6 : 8 : x : 25

8x = 150

x = 150 ÷ 8

x = 75/4
