Question

Tommy will spend 1 by 5 of this time his spend a week and study​

Answer 1

Step-by-step explanation:

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!
