1. parentheses                     your case you do -2/5=-0.4 then -3/4=-0.75 so it
2. exponents                         should look like -0.75-(-0.4)+0.4+(-0.75) next 
3. multiplication/division         add/subtract so it should look like -0.35+-0.35 
4. addition/subtraction           which equals -0.70

Do 3/7 and 7/3 represent the same length on s number line? Explain please
lutik1710 [3]
No, 3/7 and 7/3 are completely different values. If they represented the same length 3/7 would equal 7/3, which it doesn't. 3/7 = about 0.43 and 7/3 = about 2.33. 0.43 does not equal 2.33.
