Answer: ⇒ $-\frac{3}{20}$

______________________________________________________

Step-by-step explanation:

First you had to remove parenthesis first.

$\frac{7}{10}- \frac{17}{20}$

$=\frac{14}{20}-\frac{17}{20}$

Since the denominator are equal, and then you had to combine by the fraction.

$\frac{14-17}{20}$

Subtract by the numbers.

$\frac{-3}{20}$

Apply the fraction rule.

$=-\frac{3}{20}$

Any nonzero integer divided by 0 equals 0. True or false? Justify your answer.

Vanyuwa [196]

It is false. Although integers above 0 divided by 0 is 0, negative numbers can also be integers (-1,-3,-10, etc.), and when they are divided by zero, they are undefined. That means that it is not really a number.

Make up this problem yourself 3 divided by 1/2

Helen [10]

Answer:

3 : (1/2) = $\frac{6}{1} =6$

Step-by-step explanation:

Divide: 3 : $\frac{1}{2} =\frac{3}{1} *\frac{2}{1} =\frac{3 * 2}{1*1} =\frac{6}{1} =6$

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of $\frac{1}{2}$ is $\frac{2}{1}$ ) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
