Answer:
She has 11/20 yds left
Step-by-step explanation:
We take what she had and subtract what she gave away
9/10 - 7/20
We need to get a common denominator of 20
9/10 *2/2 - 7/20
18/20 - 7/20
11/20
She has 11/20 yds left
Answers:
A. -12 (6x-5)
C. 6(-12x+10)
Check out the answer A
-12(6x-5)=-12(6x)-12(-5)=-72x+60
Check out the answer C
6(-12x+10)=6(-12x)+6(10)=-72x+60
When you add and subtract be sure that the two fractions have the same denomination, and then add/subtract the numerators. I always do cross multiplication of the two fractions to obtain the same denominators-although there are various ways to do this.
Multiplying fractions is simply straight across.
Dividing fractions:
Keep, change, flip.
Keep the first fraction the same, change the sign to its opposite (ex:division flips to multiplication), and flip the numerator and the denominator of the second fraction. Then, preform the arithmetic from your "new" problem.
