Can you explain how to solve this math problem: Arianna plants a garden that has 10 rows of flowers with 20 flowers in each row. Currently, only 4/5 of the planted flowers have bloomed. How many flowers in Arianna's garden have bloomed?
Arianna planted 10 x 20 = 200 flowers in her garden.
Out of the 200, 200 x 4/5 = 160 flowers that have currently bloomed.
