Answer:
25
Step-by-step explanation:
it is given that for every 5 yellow flowers, there are 9 total flowers,
i.e yellow flowers : total flowers = 5:9
Expressed as a fraction:
yellow flowers as a fraction of total flowers = 5/9
given there are 45 flowers in total
number of yellow flowers = yellow flowers as a fraction of total flowers x total flowers
= (5/9) x 45
= 25
