Sherman goes golfing every 6th day and brad goes golfing every 7th day If Sherman and Brad both went golfing today, how many days until they will go golfing on the same day again?

42 days

Step-by-step explanation:

lest's take a look at the days when Sherman Brad will each go golfing

Sherman goes golfing 6th day.

<-0---6---12---18---24---30->

Brad goes to golfing every 7th day.

<-0---7---14---21---28->

They havent golfed on the same day yet, so let's keep gpoing!

When we keep going, we see that the multiples first meet at 42.

Sherman

<-0---6---12---18---24---30---42---48->

Brad

<-0---7---14---21---28---35---42---49-->

Mathematically, we say that 42 is the least common multiple of 6 and 7. In math notation this looks like:

lcm (6, 7) = 42

Sherman and Brad will be golfing on the same day again in 42 days.
