Yes please

anonymous · Answer

so since they are similar they have a same ratio

so i got 10.5/7 which gave me 1.5

so then i used 9/6 which game me 1.5

then i used 7.5/4.5 which did not give me 1.5 but 1.7 

so then i multiplied 4.5 by 1.5 and it gave me 6.75 which is not part of the answers

so i divided 7.5 by 1.5 which gave me 5 and it was one of the answers
