#3) - this one needs common demoninators -2/7-2 3/5+1 2/7-(-2/5)= -2/7 will become -10/35 2 3/5 will become 2 21/35 1 2/7 will become 1 10/35 -10/35 - 2 21/35 = -2 31/35 -2 31/35 + 1 10/35 is really subtracting and keeping the sign from the higher number (negative here) = -1 ...

just in case you're still stuck on the 2nd & 3rd ones - one more thing to remember: when you add/subtract fractions, they need common denominators #2) (-3)-2.2-9-(-12)= (-3) - 2.2 = -5.2 - 9 - (-12) -5.2 -9 = -14.2 -(-12) *remember the -(-12) is really adding -14.2 + 12...

**Math**

you have to remember that when you subtract a negative, you really add it - the () were used in your problems to section off numbers 8-(-2/3) would be the same as 8 + 2/3
