Not if the fraction is positive. But yes if the fraction is negative. Study the rules of multiplication and division by integers, and you wil see why. Multiplication by a fraction is simplty multiplication by one integer followed by division by another (or the other way round).

Does an inequality sign change in an equation when both sides are multipled or divided by negative number?
The sign changes if you multiply/divide by a negative number. It stays the same if you add/subtract by a negative number.
When solving an inequality when is it necessary to change the direction of the inequality symbol?
When the two sides of the inequality are multiplied or divided by a negative number or term or expression.
When do you change the direction of an inequality symbol?
When a side is multiplied or divided by a negative number.
Why does the inequality sign change when both sides are multilpied or divided by a negative number.Does this happen to equations?
It changes because the number may be lesser than the original equation. The greater the negative number the more likely the inequality sign will change.
How do you change a division problem into a fraction?
Fractions are division problems. The line in a fraction can be read as "divided by." 2/3 is actually 2 divided by 3.
Is 2over3 larger or 5over7?
The way to answer this kind of question is to change each of your fractions in to fractions with a common denominator. 2/3 =14/21 (I multipled both the numerator and denominator by 7.) 5/7= 15/21. (I multiplied both the numerator and the denominator by 3.) 5/7 is larger than 2/3
How do you change the dessimilar fractions to similar fractions?
to change dessimilar fractions to similar fractions you divide
1and a half divided by 2 and a half?
0.5
Why does the inequality sign change when both sides are multiplied or divided by a negative number Does this happen with equations Why or why notWrite an inequality for your classmates to solve I?
-x > a iff** x < -a This is easy to see intuitively by coloring a number line. ** "if and only if"
How do you change fraction to a mixed number?
You do the numerator divided by the denominator, then simplify the fractions if you can. (this is how you change a improper fraction to a mixed number, you cannot change a proper fraction to a mixed number)
Can fractions be added to decimals?
Yes providing you change the fractions into decimals or change the decimals into fractions
How do you simplify fractions such as 45 over 50?
45/50=9/10 I multipled the numerator and the denominator by the same number: 45/50*(0.2)/(0.2)=9/10 0.2/0.2 equals 1, and multiplying any number by 1 does not change its value.
