Answer 2

Question : 2/7th of the flowers in a vase are red, 3/7 th of them are white and the rest are yellow. If the vase has 21 flowers, then how many flowers are yellow?

Answer : 6 flowers

Step by step explanation :

Given :

There are 21 flowers in the vase.

Number of red flowers are 2/7 of total number of flowers

= (2/7) × 21

= 6

Number of white flowers are 3/7 of total number of flowers
