Hi! i think it’s d, just by process of elimination!! it cant be any of the others, and d estimates to be right.
257,650 rounded to the nearest hundred is 257,700 because it is right at the border (50) we have to round up.
Roberto paints 1/6 of a room in 1 hour.
Julio paints1/8 of a room in 1 hour.
Working together, they paint (1/6 + 1/8) = (4/24 + 3/24) = 7/24 room per hour.
The reciprocal unit rate is 24/7 hour per room = <em>3-3/7 hours</em> per room.
Step-by-step explanation:
12,000 views = 4 hours
=> 30,000 views = 4 * (30000/12000) = 10 hours.
Hence it will take 10 hours.
An example would be money! Money is a real life situation
