What is minus times minus?

What is minus times minus?

You may notice people “canceling off” minus signs. They are taking advantage of the fact that “minus times minus is plus”. For instance, suppose you have (–2)(–3)(–4). Any two negatives, when multiplied together, become one positive.

How do we add fractions with different denominators?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

How do you turn a negative fraction into a positive?

One way is to multiply the denominator by . But that would change the number from a negative to a positive. If you just want your fraction to look different but represent the same number, you have to perform the same operation to the numerator that you perform to the denominator.

Does dividing two negatives make a positive?

Two negatives make a positive, so a negative number divided by a negative number equals a positive number. For example, -8 / -2 = 4.

Can you reduce a negative fraction?

You factor the numerator and denominator to determine their GCF. Then you divide both the numerator and denominator by the GCF. Finally, you can’t forget to replace the negative sign once you have written your new fraction.

When you flip a negative fraction does it become positive?

No, the rule for division is that you multiply by the reciprocal. The reciprocal of a negative number is also a negative number. It is by definition the number you would multiply a given number by to get an answer of 1.

What happens if the denominator is 0?

The denominator of any fraction cannot have the value zero. If the denominator of a fraction is zero, the expression is not a legal fraction because it’s overall value is undefined. are not legal fractions. Their values are all undefined, and hence they have no meaning.

What is difference between numerator and denominator?

The top number in a fraction. Shows how many parts we have. (The bottom number is the Denominator and shows how many equal parts the item is divided into.)

What is called denominator?

The definition of the denominator states that it is the number below the horizontal line of the fraction that acts as the divisor of the numerator. It is the bottom number in a fraction that shows the total number of equal parts an object is divided into. 1.
