if 325 cases of 24 cans of soup,227 cases of 48 cans of soup . Estimate first.then find how many 12 cans of soup can made a case
Kryger [21]

Answer:

1,558 cases of 12 cans of soup can be made

Step-by-step explanation:

<em>Here, we want to calculate how many cases of cans of soup can be made; </em>

In the first part, we had 325 cases of 24 cans Now, if we split the 24 cans into 2 , we have 12 cans ;

So the number of cases is now 325 * 2 = 650 cases

In the second part, we had 227 cases of 48 cans.

If we split 48 cans into 4 , we can have 12 cans.

So the new number of cases here become 227 * 4 = 908 cases.

So the total number of cases we have will be; 908 + 650 = 1,558 cases

Hope it helps :)
