Solve the following expression:
Let's begin by converting 1.4 into a simple fraction:
Let's now convert 7 into a simple fraction:
The resulting exercise is as follows:
Let's proceed to convert the division exercise into a multiplication exercise, not forgetting to swap the numerator and denominator in the second fraction:
Let's now combine into one multiplication exercise:
Let's proceed to break down 14 into a multiplication exercise:
Next let's reduce the 7 in both the numerator and denominator obtaining the following:
Let's proceed to break down the 10 into a multiplication exercise:
Finally let's reduce the 2 in both the numerator and denominator to obtain the following solution:
What will be the sign of the result of the next exercise?
\( (-2)\cdot(-4)= \)
Think of it this way: division is the opposite of multiplication. Since , we know that . The negatives cancel out!
No! You must track the signs throughout the entire process. The sign rules apply to the final result, not individual steps. Work with the negatives from start to finish.
Converting to multiplication makes the problem easier to solve step-by-step. Dividing by a number is the same as multiplying by its reciprocal, so -1.4 ÷ -7 becomes -1.4 × .
Multiply your answer by the divisor: . Since this equals our original dividend, the answer is correct!
Try the decimal approach first: -1.4 ÷ -7 = 1.4 ÷ 7 = 0.2. Then convert 0.2 to . Both methods should give the same answer!
