Answer:
2 7/12
Step-by-step explanation:
−512−−93=?
Since the the second fraction is negative and you are subtracting, remove the negative sign and switch the operation to addition.
The equivalent equation is
−512+93=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-5/12, 9/3) = 12
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(−5/12×1/1)+(9/3×4/4)=?
Complete the multiplication and the equation becomes
−5/12+36/12=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
−5+36/12=31/12
This fraction cannot be reduced.
The fraction
31/12
is the same as
31÷12
Convert to a mixed number using
long division for 31 ÷ 12 = 2R7, so
31/12=2 7/12
Therefore:
−5/12−−9/3=2 7/12

I believe this is correct, if not lmk!
Answer:
Equation: 5.5x = 168.5
Solution: 30 shirts
Step-by-step explanation:
First, create the equation where x is the number of shirts.
Since each shirt is $5.50, the cost of the shirts will be 5.50x
Set this equal to 168.50, since that is how much money Kareendeep has.
So, the equation will be 5.5x = 168.5
Now, solve this for x, the number of shirts she can buy:
5.5x = 168.5
Divide each side by 5.5
x = 30.6
Since we can only have a whole number of shirts, she can only buy 30 shirts.
So, the answer is 30 shirts.
Answer:
Step-by-step explanation:
example :
2 1/4 + 3 1/2
you can either turn them to improper fractions, find the common denominator, and then add them and then convert that answer to a mixed number
2 1/4 + 3 1/2 = 9/4 + 7/2 = 9/4 + 14/4 = 23/4 = 5 3/4
OR
separate them....add the whole numbers, then the fractions
2 1/4 + 3 1/2 .......2 + 3 = 5.....1/4 + 1/2 = 1/4 + 2/4 = 3/4.....now put them back together and u get : 5 3/4
A. 1/20 x 200
D.10
To figure out what 5% of 200 is, you would multiply 200 by .05.
To figure out if 1/20 of 200 is 10, simply divide 200 by 20.
Hope that helps!
