Question

which of the following form a proportion 4,10,17,40

Answer 1

We use cross product. To find cross product of ratio , we multiply outer ratio called extreme and inner ratio called means

4:10::17:40

4×40 =10×17

160=170

160 is not equal to 170

So, it's not in proportion

Answer 2

Step-by-step explanation:

We know that

product of mean =product of extreme

4:10::17:40

4×40=10×17

160=170

So ,it's not in a proportion
