Kala call lasted for 0.36 minutes
<em><u>Solution:</u></em>
Given that Kala purchased a prepaid phone card for $15
Long distance calls cost $12 a minute using this card.
If the remaining credit on her card is $10.68
To find: Number of minutes her call lasted
Let "x" be the number of minutes her call lasted
Cost of 1 minute = $ 12
Total balance = $15
Remaining balance = $ 10.68
So we can frame a equation as:
Total balance = Remaining balance + Cost of 1 minute x number of minutes her call lasted
So her call lasted for 0.36 minutes

Solution
This (after combining the top 2 fractions, is a 4 tier fraction.
1/4*3/4 = 3/16
So the question now becomes 3/16 ÷ 10/3
The rule for such a question is invert (turn up side down) the second fraction and multiply.
3/16 * 3/10 Combine
(3*3)/(16* 10)
9 / 160
0.05625
Less than or equal to first equation (solid line)
less tha second equation ( the dotted line)
so its d
Answer:
Associative Property of Multiplication
Step-by-step explanation:
We are given three numbers-a,b,c.
We are given the property (ab)c = a(bc)
This implies that on the left hand side we first multiply a and b and then multiply the result by c. On the right side of the equation, we first multiply b and c and multiply a with the product of b and c.
As per the given property, the result in both the cases is the same.
This signifies the associative property of multiplication where the result is independent of the order of operation.
Hey there,
The whole number(or mixed fraction) would be: 1 2/3
The improper fraction would be: 5/3
