Step by step workout
step 1 Input values:
1/3, 2/5, 3/7, 5/9
Total count = 4
step 2 Compare all denominators of the fractions, if they are not same, find the LCM (least common multiple) for all denominators. 315 is the LCM for 3 , 5 , 7 , 9 .
step 3 Multiply LCM 315 with each numerators and denominators
= (1 x 315)/(3 x 315)+(2 x 315)/(5 x 315)+(3 x 315)/(7 x 315)+(5 x 315)/(9 x 315)
step 4 Simply the above expression to have same denominators for all fractions.
=(1 x 105)/315+(2 x 63)/315+(3 x 45)/315+(5 x 35)/315
=105/315+126/315+135/315+175/315
=105 + 126 + 135 + 175/315
step 5 Add all numerators and rewrite it in a single form.
=541/315
