Question

1.2, 1.6, 0.9, 1.2 It Is Proportion Or Not? How To Solve This​

Answer 1

Answer:

Let's convert all the decimals in fraction,

1.2= 12/10

1.6=16/10

0.9=9/10

1.2=12/10,

to heck if  they are in proportion or not,

12/10/(16/10)=9/10(12/10)

cutting all 10,

or,12/16=9/12

or,3/4(dividing by 4 )=3/4(dividing by 3 )

therefore, 3/4=3/4, so they are in proportion.
