Answer:
I would have to say that the simplest form of -5/8 - ( -4/3) would just be the answer, so that would turn out to be approximately 0.715. Keep in mind that your school or wherever the question is from may have a different method or a different meaning then how I am interpreting it to be.
Step-by-step explanation:
First, we have to figure out the parentheses, as the order of operations goes parentheses, exponents, multiplication, division, addition, and subtraction. (another way to remember this is by P.E.M.D.A.S., or Please Excuse My Dear Aunt Sally. Either way, (-4/3) is, in decimal form, equivalent to -1.34.
Next, we have to figure out -5/8, which comes out to be -0.625.
Lastly, we just subtract -5/8 - ( -4/3), which will get you the answer of 0.715, and you can round however you need to if you need to.
AS an alternative, you may also convert this into a fraction.
Answer:
0.715 = 143/200
Showing the work
Rewrite the decimal number as a fraction with 1 in the denominator
0.715 = 0.7151
Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000
0.7151 × 1000/1000 = 715/1000
Find the Greatest Common Factor (GCF) of 715 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,
715 ÷ 5/1000 ÷ 5 = 1432/00
Therefore
X = 143200
In conclusion,
0.715 = 143/200
