# please help?

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

Favorite Answer

the answer: -1/10

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.

your answer: 3/4

4. i think you already found the answer to that.

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

your answer: .3

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

hope this helps!

6.

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 /

2. 2 1/2

3. 3/4

4. 4.48??

5. 0.3

6. -7

Only fourteen, but I really did try.
