in a packet of skittles there are 27% are red and 23% are green and the rest are blue what percentage are blue?

50% are blue.

Step-by-step explanation:

The total number of skittles  in the packet will be represented by 100%. If 27% are red and 23% are green then the combination of the red and green skittles subtracted from 100 will give the percentage of the blue skittles.

27% + 23% = 50%

100% - 50% = 50%  

This means half of the skittles in the packet are blue which is 50%.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
