Today we worked in our DMIC groups to solve this problem.When you find a fraction of a number, the thing you need to do is divide the number by the denominator.

First we worked out that 105 divided by 7 was 15. Most of us drew 7 circles, we counted in 10s 7 times and then in 5s and that made 105, which left in each group.

The next step is to take the number 15, and times by the numerator, which was 4.

15x4=60.

The answer is 60.

60 mussels could be taken by fisherman - 4/7 of 105 is 60 mussels
