    STEP BY STEP SOLUTION
    2 cross times space open parentheses fraction numerator negative 3 over denominator 8 end fraction close parentheses space plus space 1 space cross times space open parentheses fraction numerator negative 6 over denominator 5 end fraction close parentheses
M u l t i p l y i n g space
fraction numerator negative 6 over denominator 8 end fraction space plus space fraction numerator negative 6 over denominator 5 end fraction
N o w space w e space c a n space t a k e space L C M space a u r space c o n v e r t space f r a c t i o n space i n t o space d e c i m a l s space
L C M space o f space 8 space a n d space 5 space i s space equals space 40
fraction numerator negative 30 space minus space 48 over denominator 40 end fraction space equals space minus 78 over 40 space equals space fraction numerator negative 39 over denominator 20 end fraction
