Answer:
7/15
Step-by-step explanation:
Determine how much she has watched.
1/3 + 1/5 The common denominator of 3 and 5 is 15. Multiply each fraction by an amount that will make the denominator 15
1/3 = 1*5/(3*5) = 5 / 15
1/5 = 1*3 / (5*3) = 3/15
Now add the two fractions together.
5/15 + 3/15 = 8/15
What is left of the movie? The whole movie = 1 so that which is left is
1 - 8/15
15/15 - 8/15
7 / 15
She has just a bit under 1/2 to go.
Answer:
b
Step-by-step explanation:
108-271+215-_____=-103
Im going to combine the first thee numbers and replace the blank with a variable, lets use x.
52 - x=-103
now I am going to subtract 52 on both sides to get the variable alone
-x=-155
Im going to multiply both sides to eliminate the negitive in the variable
x=155
If you want to check just plug 155 into the blank
108-271+215-155=-103
-163+215-155=-103
52-155=-103
-103=-103
so after checking work the blank is equal to 155.
