[1/4 Formula]
    Work: Calculate the value of equation 1386*97.9%+1386*121%+(241.9%+120%)*841 .
    Question type: Mathematical calculation
    Solution:
          1386*97.9%+1386*121%+(241.9%+120%)*841
        =1386*97.9%+1386*121%+3.619*841
        =1386*0.979+1386*121%+3.619*841
        =1386*0.979+1386*1.21+3.619*841
        =1356.894+1386*1.21+3.619*841
        =1356.894+1677.06+3.619*841
        =1356.894+1677.06+3043.579
        =3033.954+3043.579
        =6077.533
    Answer:1386*97.9%+1386*121%+(241.9%+120%)*841=6077.533
[2/4 Formula]
    Work: Calculate the value of equation (8000-3043)/(97.9+121)% .
    Question type: Mathematical calculation
    Solution:
          (8000-3043)/(97.9+121)%
        =4957/(97.9+121)%
        =4957/218.9%
        =4957/2.189
        =2264.50434
    Answer:(8000-3043)/(97.9+121)%=2264.50434
[3/4 Formula]
    Work: Calculate the value of equation 841/((97.9+121+109.2*2)/(241.9+120)*2) .
    Question type: Mathematical calculation
    Solution:
          841/((97.9+121+109.2*2)/(241.9+120)*2)
        =841/(437.3/(241.9+120)*2)
        =841/(437.3/361.9*2)
        =841/2.41669
        =347.99664
    Answer:841/((97.9+121+109.2*2)/(241.9+120)*2)=347.99664
[4/4 Formula]
    Work: Calculate the value of equation (97.9+121+109.2*2)/((241.9+120)*2.4) .
    Question type: Mathematical calculation
    Solution:
          (97.9+121+109.2*2)/((241.9+120)*2.4)
        =437.3/((241.9+120)*2.4)
        =437.3/(361.9*2.4)
        =437.3/868.56
        =0.503477
    Answer:(97.9+121+109.2*2)/((241.9+120)*2.4)=0.503477
