6w+1=9w-3
-6w -6w
1=3w-3
+3 +3
4=3w
w=1.333 or 1 1/3
You can of course use a calculator, but if you can't, just put them into improper fractions. So 2 3/4 as an example would be 11/4. So if you had 2 3/4 divided by 4 1/2, you'd have (11/4)/(9/2).
When you divide fractions, you can multiply by the reciprocal. So you'd go (11/4)•(2/9)=22/36=
11/18
(-65) + 42 = -23
when you add negetive numbers, it it just like addition but backwards.
( not subtraction)
Your answer woukd be -23.
