what is the value of -3/4-(3/-8)
(the 3/4 fraction only has the - on the 3, not the entire fraction)
a -1 1/8
B -3/8
C3/8
D 1 1/8
What I did is first find a common denominator making the equation
-6/8-(3/-8)= -9/16
this is not one of the choices
Can you please help.
Thank you
-3/4-(3/-8)
= -3/4 + 3/8
= -6/8 + 3/8
= -3/8
Thank you for your help
To evaluate the expression -3/4 - (3/-8), you need to follow the order of operations (PEMDAS/BODMAS) and simplify step by step.
Step 1: Simplify the individual fractions:
-3/4 remains as it is because the negative sign is only on the numerator (3), not the entire fraction.
3/-8 can be simplified to -3/8 by moving the negative sign from the denominator (8) to the numerator (3).
Now, the expression becomes:
-3/4 - (-3/8)
Step 2: Simplify the subtraction of two fractions:
When subtracting fractions, you need to find a common denominator. In this case, the common denominator is 8 because both fractions have a denominator of 8.
Multiply the numerator and denominator of the first fraction (-3/4) by 2:
(-3/4) x (2/2) = -6/8
The expression becomes:
-6/8 - (-3/8)
Step 3: Subtract the two fractions with the same denominator:
When you have fractions with the same denominator, you subtract the numerators while keeping the denominator the same.
-6/8 - (-3/8) simplifies to:
-6/8 + 3/8
Step 4: Add the numerators and keep the denominator the same:
-6/8 + 3/8 = (-6 + 3)/8 = -3/8
Therefore, the value of -3/4 - (3/-8) is -3/8.
