I don’t get this ath HW at all can smeone please help me and explain this to me??

my HW says

Evaluate.

1) a + b for a = 1/5, b = – 3/10

2) p/q for p = – 3/5, q = – 6/25

3)1/4 (j – k) for j= 2 1/2, k= – 1/2

4)c = d/2 for c = 1.6, d= 2.8

5)2ef for e = -1.5, f= – 0.1

6) -2 (L + m) for L= /0.5, m = 3

hey hey hey i’m wus happenin

1. Okay number one is simple math, you should know that to evaluate this problem you have to add the variables. But since the value of the variables are fractions, you need to find the common denominator, and then do the math.

2. number two is a complex fraction. first you need to find the common denominator (of 5 and 25) then clear those numbers and you’ll have the remaining numerators over each other, reduce, and your answer is..

-5/2

3. If you’ve learned the distributive property.. do not use it. Using order of operations you just first start with the parantheses with is 2 1/2 minus -1/2 . Once you’ve found the answer to that, then multiply it to 1/4.

5. just multiply 2(-1.5)(-0.1)

6. -2(0.5 + 3)– you can do that on the calculator.

hope this helps!

1) a + b for a = 1/5, b = – 3/10

1/5 – 3/10 = 2/10 – 3/10 = -1/10

2) p/q for p = – 3/5, q = – 6/25

-3/5 / -6/25 = 3/5 * 25/6 = 5/2 = 2.5

3)1/4 (j – k) for j= 2 1/2, k= – 1/2

1/4(2.5 – -.5) = 1/4(3) = 3/4

4)c = d/2 for c = 1.6, d= 2.8

1.6 = 2.8/2

1.6 = 1.4 INCORRECT

Should this be: c – d/2 ?

1.6 – 1.4 = .2

5)2ef for e = -1.5, f= – 0.1

2*(-1.5)*(-0.1) = .3

6) -2 (L + m) for L= /0.5, m = 3

-2(.5 + 3) = -2(3.5) = -7

I don’t know what you mean by /0.5, so I ignored the /

Find a common denominator for each fraction by multiplying because you can only combine like terms. Ex: If you multiply 1/5 by 2 over 2, you get 2/10. 2/10 + 3/10 = 5/10 –> 1/2 Good luck!
