Let each student eats 1 bread a day. Therefore, 30 students for 4 days will eat: 30 * 4 = 120 breads

=> Now if 10 more children are added: 30 + 10 = 40.

=> 120 bread will last for \(\frac{120 }{ 40}\) = 3 days.

amount = rate * time

30 * 4 = 120 rations of bread.

If 10 more students are added: 30 + 10 = 40 students

120 / 40 = 3 days.

Great explanation Basshead
Quick question why is below method wrong? Where's my thinking gone wrong?
Could you kindly help clarify? Thanks

30/4 = 40/x
x = 16/3
