Step-by-step explanation:

you know how to multiply fractions ?

a/b × c/d = (a×c)/(b×d)

the 2 top parts are multiplied and the 2 bottom parts are multiplied.

the existing answers in "Model" are wrong.

when we multiply the actual size by the scaling factor, we get the model size.

2 1/3 = (6+1)/3 = 7/3

7/3 × 2/5 = 14/15

this is s little bit smaller than 1, and definitely not 1 1/3 (more than 1).

similar with the width.

1 3/7 = (7+3)/7 = 10/7

10/7 × 2/5 = 20/35 = 4/7 (and not 3/4)

so, this is all wrong.

the question is, if maybe the specified scaling factor of 2/5 is wrong.

so, let's see what the scaling factual is for the given model sizes.

7/3 × f = 1 1/3 = (3+1)/3 = 4/3

7f = 4

f = 4/7

now let's try this scaling factor for the width :

10/7 × 4/7 = 40/49

no, this is also not 3/4 (not even close). this is much closer to 4/5.

therefore, I assume now that the actual and scale numbers are correct, and we calculate all the correct model numbers.

so, again

the model length is actually 14/15

the model width is 4/7

the model height is

(8+1)/8 × 2/5 = 9/8 × 2/5 = 18/40 = 9/20

the model door width is

6/7 × 2/5 = 12/35

the model door height is

7/8 × 2/5 = 14/40

and because the scaling factor (2/5) is smaller than 1, actually smaller than 1/2, the model numbers will be smaller then even half the actual numbers. as our results above show.

the answer is d. 75%
