Lucy is a dress maker. She sees 4/7 of a dress in 3/4 hour. How many dresses will Lucy sew in 1 hour

She will sew 5.

Step-by-step explanation:

I did this by taking 3/4 an hour or 45 minutes and divided by 4. That gives me the average sewing speed for one dress. Which was 11.25. Then I did 60 divide by 11.25 and you would get 5.3333. And you only count the whole number for a whole dress. So the answer is 5.

If the question is saying she is only sewing one dress and it already is 3/4 an hour. The answer is she wont have finshed that one dress within the hour

for this we'll have to get 4/3

Multiply 3 from 4 which will give us 4/7 x 4/3. That should give us 1 hour: 16/ 21 dresses

hope this helps lmk :)
