(-7/3) + (3/4),,,,,,if we just did decimals on a calculator,,= -1.5833,,,,but they undoubtably want to use fractions
.
The LCD of 3 and 4 is 12
.
(-28/12) + (9/12),,,,now to add opposite signs,,,take difference and use biggest sign
.
( - 19/12)
.
checking to original decimal technique,,-19/12 = - 1.5833,,,ok
