Answer 1

Annette is 40 1/4 inches tall.

Explanation:

The only fraction you need is the one equivalent to the decimal 0.25. Of course, that decimal means 25/100, which reduces to 1/4. You can also use the fraction (1/2) to help you compute half of 70 if you like.

Eric is 70 inches tall.

Pablo is half that, so is (1/2)·(70 inches) = 35 inches.

Annette is 5 1/4 inches taller, so is (35 +5 1/4) inches = 40 1/4 inches.

Annette is 40 1/4 inches tall.
