Math questions, help please?

Here’s the 2 math problems:

1.) 8/12 – Y = 8/96

Y= ?

2.) Right triangle

a = 60°

b = 90°

c = ?

Thank you!

Ok, for the first one the easiest way to do it is to reduce that 8/96 down to lowest terms, which would be 1/12 (does that makes sense?). Now, the problem becomes:

8/12 – y = 1/12

Isolate -y on one side of the equals sign like this:

-y = 1/12 – 8/12

(I moved the 8/12 to the other side, and changed its sign when I did so).

So now you solve that, and get:

-y = -7/12

Now, you can multiply both sides by -1 to get rid of that negative sign in front of the y, and you end up with

y = 7/12

For the other problem, what you have to remember is that the sum of the angles in any triangle will always add up to 180. You have two of them already (and 90 + 60 = 150). So, that means that the remaining angle has to be 30 degrees (180-150=30)

I hope that helps. You can email me at [email protected] if you have other questions. Good luck.

for question 1

first, isolate Y

8/12 – Y + Y – 8/96 = 8/96 + Y – 8/96

cancel out terms to get

8/12 – 8/96 = Y

notice that 96 is a multiple of 12 * 8

so you could write 8/96 = 8/ (12*8)

the 8’s cancel and you’re left with 1/12, now your fractions have a common denominator

8/12 – 1/12 = Y Solve for Y

Y = 7/12

Now for question 2

All angles in a triangle add up to 180 degrees, form an equation.

a + b + c = 180 and you’re given a and b

60 + 90 + c = 180 combine like terms

150 + c = 180 subtract 150 from each side

150 – 150 + c = 180 – 150 simplify

c = 30 that’s the angle you’re looking for!

8/12-Y=8/96 means same as this below. The simbol such as – or + have to change when they move another site. You need Y default, so you have to make the -Y into +Y, whcih means Y. So you will see the another fomula now.

8/12-8/96=Y

* You have to make the denominator as same as 96.

(8×8/12×8) – (8/96) = Y

64/96-8/96=Y

56/94 * 56 came from 64-8

after all the answer is

7/12 –> to get this answer from 56/94, start to use number 2 to reduce the numbers and reduce until you can not reduce those numerator and denominator, and then you will see this answer, 7/12

Good luck. it is good to ask when you don’t know .. don’t be shy…

1) y= 7/12

8/12-y=1/12

-1/12 -1/12

7/12-y=0

+y +y

7/12=y

2) 30
