Felix can finish weaving a mat in 4 1/5 hours. If he spends 1 3/4 hours doing his daily , how many days would it take him to finish one mat?

NOTE: Please use as the solution the solution on bold, not on the italic one. It's more complicated. 

This is done by dividing 4 1/5 by 1 3/4.
We can convert this things on decimal to be more easy, seriously.

4 1/5 ÷ 1 3/4 = x
4.2 ÷ 1.75 = x 
2.4 = x
2 2/5 = x

So therefore, he can finish one mat in 2 days, and 4 hours.

We shouldn't convert for it to be more easy-to-understand. Instead, use the divisor's reciprocal.
4 1/5 ÷ 1 3/4 = x
21/5 ÷ 7/4 = x
21/5 × 4/7 = x
84/35 = x
2.4 = x
2 2/5 = x

So therefore, he can finish one math in 2 days, and 4 hours.
