The weight of 9 bags is 5.4 blocks
<em><u>Solution:</u></em>
Given that,
5 bags weigh the same as 3 blocks
We have to find how many blocks will 9 bags weigh
Let "x" be the weight of 9 bags
Then,
5 bags weigh the same as 3 blocks
9 bags weight the same as "x" blocks
From proportion we can say,
5 : 3 : : 9 : x
Therefore,
Thus the weight of 9 bags is 5.4 blocks
Answer:
