What is the value of the numerical expression 5/8-5/12(3-1/4)+2/3

Answers

make bottom numbers same
find least common multipules of 8,12,4 and 3
8=2 times 2 times 2
12=2 times 2 times 3
4=2 times 2
3=3
lcm=2 times 2 times 2 times 3=24

5/8 times 3/3=15/24
5/12 times 2/2=10/24
3/1 times 24/24=72/24
1/4 times 6/6=6/24
2/3 times 8/8=16/24
we now have
15/24-10/24(72/24-6/24)+16/24
pemdas
simplify parenthasees first
72/24-6/24=66/24

now we have
15/24-10/24(66/24)+16/24
multiply
15/24-660/576+16/24
make same bottom number
15/24 times 24/24=360/576
16/24 times 24/24=384/576
360/576-660/576+384/576
84/576
7/48

answer is 7/48

-2/3 qould be classifide as a whole,natural,rational, and irrational

Answers

-2/3 is not whole, not natural, and not irrational.

From that list, the only thing it is is rational.

rational, as it is negative, a fraction, but also a fraction whose decimal form is repeating. so, since its a negative fraction, it can't be whole or natural, and since its decimal form is repeating, it's rational and not irrational. Hope that made sense

Edit:whole numbers and natural numbers are pretty much the same, since in nature there aren't really any negative things, like a tree isn't -11 feet tall

Write 15.1 as a fraction

Answers

If you want to convert 15.1 into a fraction, you can do it like this:
15 equals to 15/1 and 0.1 equals to 1/10
The result is 15 1/10.

If you want to make it a pure fraction, you haveto make one additional step:
because you want to add 15/1 and 1/10, youhave to get the same denominators, so 15/1 changes to 150/10.
Now, you can add 150/10 and 1/10.The result is 151/10.

15 1/10
