Answer:

21 inches

Step-by-step explanation:

If the boy is 25% smaller, that means his current height is 75% of his previous height. 75% of 28 is 0.75 * 28 which is 21.

Hope this helps :)

Answer:

35 inches tall. (This is assuming they want him to be 25% taller. Using the past tense of 28, I assume this is growth.)

Step-by-step explanation:

25% is 25/100 therefore we get 1/4 which gives us 28/4 = 7.

So this makes the boy 7 inches taller than 28.

28 + 7 = 35

Making him 35 inches tall.
