Question

Proportional RelationshipsComplete this table2 | 35 | ?? | 10.5? | 151 | ?

Answer 1

`(2)/(3)=(5)/(7.5)=(7)/(10.5)=(10)/(15)=(1)/(1.5)`
`(2)/(3)=(5)/(x);x=(5\cdot3)/(2)=(15)/(2)=7.5`
`(2)/(3)=(x)/(10.5);x=(2\cdot10.5)/(3)=7`
`(2)/(3)=(x)/(15);x=(2\cdot15)/(3)=(30)/(3)=10`
`(2)/(3)=(1)/(x);x=(1\cdot3)/(2)=(3)/(2)=1.5`

Here, we take two sets, including the one with the unknown. Then we use cross multiplication to solve for the unknown, until all the unknowns are solved since all of them are direction proportion of each other

Ansswer:

`(2)/(3)=(5)/(7.5)=(7)/(10.5)=(10)/(15)=(1)/(1.5)`
