Question

2/5- -3/4 what would be the answer?

Answer 1

For this case we must simplify the following expression:

`\frac {2} {5} - (- \frac {3} {4})`

By definition of the law of multiplication signs we have to:

`- * - = +`

So, rewriting the expression we have:

`\frac {2} {5} + \frac {3} {4} =\\\frac {4 * 2 + 5 * 3} {5 * 4} =\\\frac {8 + 15} {20} =\\\frac {23} {20} = 1.15`

Thus, the answer in decimal form is 1.15.

Answer:

`\frac {23} {20} = 1.15`
