Let's assume that there are a total of 100 flowers in the garden.
We are given that of the flowers are roses, which means there are roses in the garden.
We are also given that of the roses are white, which means there are white roses in the garden, and that of the roses are pink, which means there are pink roses in the garden.
To find the fraction of the total flowers in the garden that are white or pink roses, we need to add the number of white roses and pink roses, and then divide by the total number of flowers in the garden.
The number of white or pink roses is the sum of the number of white roses and the number of pink roses, which is:
= white roses + pink roses
= ( of the roses) + ( of the roses)
= +
= roses
The fraction of the total flowers in the garden that are white or pink roses is:
= (number of white or pink roses) / (total number of flowers)
= / 100
Therefore, of the total flowers in the garden are white or pink roses.
