Question 459144
I want to find 7/12 of 1560. I'm really saying, "Divide 1560 into 12 groups and figure out how many are there all together in 7 of those groups." 
===
Divide 1560 into 12 groups.
{{{1560/12=130}}}
Each group has 130. We want to know how many are in 7 groups, so we multiply.
{{{130*7=910}}}
===
There will be 910 women among the 1,560 runners.
