Question

Jenna competes in the high jump. Her best jump in the first meet is 414 feet. Her best jump in the second meet is 456 feet. Enter an expression, using equivalent fractions with a common denominator, to model how much the height of her jump increased.

Answer 1

Answer: $\dfrac{7}{69}$ of height has been increased in second jump from the first jump.

Step-by-step explanation:

In first meet, height of best jump = 414 feet

In second meet, height of best jump = 456 feet

Increase in height = 456 feet - 414 feet

= 42 feet

The fraction of increased in height = $\dfrac{\text{Change in height}}{\text{previous height}}$

$=\dfrac{42}{414}\\\\=\dfrac{7}{69}$

Hence, $\dfrac{7}{69}$ of height has been increased in second jump from the first jump.
