The expression given is (1/4)- (3/7)×(7/8)
In order to solve this we first need to find the Greatest Common Factor
·GCF=56
Proof: 56/7=8, 56/8=7, 56/4=14
Now we multiply each fraction by the given factor to create the new fractions.
·(14/56)-(24/56)×(48/56)
Next we multiply (24/56) and (48/56), due to the laws of PEMDAS
·(1152/3136)
Next to make this easier, we can devide the denominator by 56 to get the number we need to finish the problem
·56×56=3136
·(784/3136)=(14/56)
Next we subtract
·(784/3136)-(1152/3136)
And we get
·(-368/3136)
Next we simplify
·(-23/196)
which is roughly -(1/8)
In conclusion your answer is -(1/8)
