Tommy will spend 1/5 of this time weekend studying for his four final exams.what fraction of the weekend will he spend for each of his 4 exams if he spends the same amount of time for each exam?

Answer 1

Hi!

I hope I can help you understand this question :)

If Tommy is spending 1/5 of his time studying four exams then we have to equally split that 1/5 of time over the 4 subjects. To do this, we divide 1/5 by 4.

Now when it comes to fractions, to make it easier to visualize, we'll use 1/5 ÷ 4/1.

When we divide fractions, we flip the one we are dividing by (4/1) and multiply.

To multiply fractions we just multiply straight across.

So we have 1/5 x 1/4.

On the top, we have 1 x 1, that's 1.

On the bottom we have 5 x 4, that's 20.

So our final answer is 1/20!

I hope that helps and let me know if you have questions!

Answer 2

1/5 ÷ 4 = 1/5 x 1/4 = 1/20 of his time
