Divide 450 grams into ratio 7:2

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.
