The two square pyramids are similar. the side length of the smaller pyramid 3/4 the side length of the larger pyramid. which fraction represents the ratio of the smaller pyramid to the base area of the larger pyramid

9/16

Step-by-step explanation:

The base of the square pyramid is a square.

By definition, the ratio of the areas of two similar squares is the squared of the ratio of the lenghs of the sides.

Therefore, keeping this on mind and knowing that the ratio of the sides is 3/4,  you can calculate the ratio of the smaller pyramid to the base area of the larger pyramid as you can see below:

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
