Hey there!
When we multiply fractions and whole numbers, we simply take that whole number and put it over them, and just multiply across. That gives us:

Notice how it's four, because when we have a fraction, we divide. 8 divided by 2 equals four. Next:

4/4 is equal to 1 because 4 divided by 4 is one. 4 goes into 4 once. Next, we have:

That's because 6/3 = 2.
Hope this helps!
Answer:
x = 1
Step-by-step explanation:
the angle 2 is equal to 52, because triangles add up to be 180, and 180 - 76 and divided by two is 52. 52 = 4x + 12. Divide both sides by four, then subtract 12. x = 1
So there is a rule
(+)(+)=+
(-)(+)= -
(+)(-)= -
So now if you subtract 6 with 7 you will end up having -1 as you’re answer. Hope this helps
