Question

Two similar triangles are in the ratio 2:3. If the sides of the bigger triangle are 15 units, 12 units and 9 units, then the length of the shortest side of the smaller triangle is

a. 8 units
b. 6 units
c. 9 units
d. 5 units

Answer 1

It is 6 units because if you divide 9 by 3 you get 3 and you multiple that by 2 to make it 6:9 which is equal to 2:3
