I find Math fun because Math issues aren't simple to solve, but figuring out the solution may be quite rewarding. Remind kids that some issues are simpler to solve than others, and that figuring it out is part of the fun. Bring a feeling of adventure and inquiry to math class. Math promotes critical thinking and problem-solving abilities. Learning to look at an issue and come up with a strategy, whether it's a math problem or a life problem, is a crucial ability to have. You might think of arithmetic as searching for an answer in a book or on a worksheet, but it always begins with a question or a thought. Students' curiosity and enthusiasm are piqued when they are encouraged to begin by wondering.

]]>The solution is right.

Good!

The solution has already been given in #4 above.

This is just to inform you.

]]>x/5+(5 .10-45)/10

By multiplying:

To get the simplest form first of all we will multiply 5 with 10.

x/5+(5 . 10-45)/10

x/5+(50-45)/10

By multiplying 5 with we got 50

By subtracting:

To make it simpler we will subtract 45 from 50.

x/5+(50-45)/10

x/5+5/10

Reducing the fractions with 5.

x/5+5/10

x/5+1/2

The real reason to reduce the fraction is to rewrite it in the simplest way.

Finding the common denominator:

x/5+1/2

x/5+(5 .1/2)/10

Combining the fractions with a common denominator:

x/5+(5 .1/2)/10

(x+5 .1/2)/5

By multiplying the number:

(x+5 .1/2)/5

(x+5/2)/5

Answer:

(x+5/2)/5
