Michael and his sister Mel share the job of mowing the grass in their yard. Michael mows ⅓ of the yard, and Mel mows the rest. Mel can mow ¾ of the entire yard in an hour.How long will it take Mel to finish mowing the yard?? Also after Michael mows 1/3 of the yard what fraction of the yard does mel need to mow?

Respuesta :

Michael Mows = 1/3 of the yard

Mel mows the rest = 1-1/3 = 2/3 of the yard

Mel mows = 3/4 of the yard in an hour

After Michael mows 1/3 of the yard what fraction of the yard does Mel need to mow?​

1- 1/3 = 2/3 of the yard

How long will it take Mel to finish mowing the yard??

2/3 / (3/4) = 8/9 hours = 0.89 hours
