Do you mean this number:
?
The we have to simplify the fraction part, since the nominator is bigger than the denominator.
How many denominators fit into the nominator? 20: 4=5
5! so
is simply 5 and we can add it to the main number:
175+5=180
Answer:
300+120=420divied by 18=?
Step-by-step explanation:

<u>Given:</u>
Number of pages read by Jack = 40 per hour
Rate of reading by Dave =3/5 of a page in a minute
<u>To find:</u>
The person who reads faster and by how many minutes.
<u>Solution:</u>

(60 minutes = 1 hour)
pages in an hour
The difference between pages read by Jack and Dave is 
Therefore, Jack reads faster than Dave by 4 pages.
