A can do a work in 35 days while B can do the same work in 140 days. What percentage of the work will be done in 14 days if they work together?

½

Step-by-step explanation:

Amount of work A can do in a day: 1/35

Amount of work B can do in a day: 1/140

Amount of work A can do in 14 days: 1/35×14=⅖

Amount of work B can do in 14 days: 1/140x14=1/10

Total amount of work done in 14 days= ⅖+1/10=½

the correct answer is 828.07

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
