Question

1. Are the following numbers in proportion? (1) 16, 18, 8,9

Answer 1

Answer:

Yes the following numbers are proportional

Step-by-step explanation:

If a number is said to be in proportion when

a : b :: c : d

Taking

a= 16

b=18

c=8

d=9

Now finding the ratio of a and b we get

16 : 18

= 8 : 9

Again if we see the ratio of c and d we get 8 : 9

So yes they are proportional

Answer 2
