what is 12 8/15 - 7 + 7/15 + 15 in simplest form?
o 20 15/15
o 21
o 41 15/15
o 35
To simplify the expression -12 - (-6), we can rewrite it as -12 + 6.
-12 + 6 = -6
Therefore, the correct answer is D. -6.
To simplify the given expression, we need to add and subtract the numbers accordingly.
12 8/15 - 7 + 7/15 + 15
First, let's simplify the mixed number 12 8/15. The whole number part is 12, and the fraction part is 8/15.
12 + 8/15 = 12 * 15/15 + 8/15
= (12 * 15 + 8)/15
= (180 + 8)/15
= 188/15
So the expression becomes:
188/15 - 7 + 7/15 + 15
Now let's add and subtract the remaining numbers:
188/15 - 7 + 7/15 + 15 = (188 - 7*15 + 7)/15 + 15
= (188 - 105 + 7)/15 + 15
= (83 + 7)/15 + 15
= 90/15 + 15
= 6 + 15
= 21
Therefore, the simplified form of the expression is 21. So the correct answer is option o 21.
JoJo had 1 1/2
cups of sugar. She used 3/4
cup for her cookies. How much does she have left?
To find out how much sugar JoJo has left, we need to subtract the amount used for the cookies from the initial amount she had.
JoJo had 1 1/2 cups of sugar, which can be rewritten as an improper fraction: 3/2 cups.
She used 3/4 cup for her cookies.
To subtract fractions, we need to have a common denominator, which in this case is 4.
3/2 - 3/4 = (3 * 2)/(2 * 2) - 3/4
= 6/4 - 3/4
= (6 - 3)/4
= 3/4
So, JoJo has 3/4 cup of sugar left.
If we want to express this as a mixed number, we can write it as 0 3/4 or simply 3/4.
Therefore, JoJo has 3/4 cup of sugar left.
