Option (D) is correct
Answer:
13/18
Step-by-step explanation:
- 6.5 · 1/9 = 6 5/10 · 1/9
- 6 5/10 · 1/9 = 6 1/2 · 1/9
- 6 1/2 · 1/9 = 13/2 · 1/9
- 13/2 · 1/9 = 13/18
Therefore, 6.5 · 1/9 = 13/18.
False. If the area is 0 that means there is nothing there, therefore the area of a polygon cannot be zero.
Let us assume the common ratio = x
Then from the given question we can write
7x + 2x = 450
9x = 450
x = 450/9
= 50
Then the quantity 450 grams can be divided in the ratio of 7 : 2 by = 7x:2x
= (7 * 50) : (2 * 50)
= 350:100
I hope this is the answer you were looking for and the procedure for finding the answer is also absolutely clear to you.
