Hey!!!
_____________________________
●In 1st one,we can know that it is in direct by multiplying or dividing like,In first table by dividing we get,21÷7=3,27÷9=3 and 39÷13=3
If they are equal then we can say this table is in direct proportion.
●In 2nd one,now we can see after multiplying we get 8×6=48,12×4=48 and 3×16=48 as they are equal we can say it is in indirect proportion.
