Which of the follwing equations has a quotient with a remainder?

Reptile [31]

Answer: Choice 2) A, B, C

====================================

Explanation:

Use a calculator to find that,

946/32 = 29.5625
1157/11 = 105.1818 approximately
3524/44 = 80.0909 approximately
37392/82 = 456

The first three results have a decimal portion as the answer. So there is a remainder here. The remainder is the leftover bit that couldn't make another full value. Only choice D results in a whole number that isn't a decimal value, so this does not have a remainder.

As a smaller example, let's say we had 20 cookies and 3 people. If we want to divide the cookies evenly, then each person gets 20/3 = 6 full cookies and there would be 2 cookies left over (6*3 = 18 are eaten so 20-18 = 2 is left over). Notice that 20/3 = 6.67 approximately. The non-whole number decimal value indicates we have a remainder. If we had 21 cookies, then each person gets 21/3 = 7 full cookies with nothing left over, so there's no remainder here.

Alice has a total of 12 dimes and nickels. She has 2 more nickels than dimes

valkas [14]

This is a problem of system of linear equations in two variables. This concept of mathematics is very useful in real-life problems. You can solve a system by finding the solution. A solution of a system are the values of the variables that satisfies each equation in the system. So by knowing these concepts we can get a system of equation by analyzing each statement step by step, that is:

1. Alice has a total of 12 dimes and nickels.

Let the variables:

$D: Dimes \\ N:Nickles$

1st. Equation:

$D+N=12$

2. She has 2 more nickels than dimes

2nd Equation:

$N=D+2$

Therefore our system of linear equations is:

 $(1) \ D+N=12 \\ (2) \ N=D+2 \\ \\ Substituting \ (2) \ in \ (1): \\ D+(D+2)=12 \therefore 2D=10 \therefore D=5 \\ \\ Solving \ for \ N \ in \ (2): \\ N=5+2=7$

Conclusion:

Alice has 5 dimes and 7 nickels.
