40% of the flowers in the garden are roses the rest of the flowers are daiseis if 8 flowers are roses how many flowers are there

lidiya [134]

Draw a rectangle, shade in 40%, that's roses, the other 60% are daisies.
2/5 of the garden is 8 roses, 1/5 of the garden is 4 flowers, 3/5 is 12 flowers, so if 2/5 is 8 roses, 3/5 is 12 daisies.
8+12=20
There are 20 flowers in total.
