Answer:
7/10 trees in the park are deciduous
Explanation:
A fraction compares part of a quantity to the entire quantity, as shown by the expression part / whole.
Since 280 trees are part of the whole 400 trees in the park, we have:
280 / 400
Both 280 and 400 can be divided by 40. Divide both the numerator and denominator by 40 allows us to simplify the fraction:
(280 / 40) / (400 / 40)
7/10
Thus, 7/10 of the trees in the park are deciduous.
