If you would like to know how many hours will Lena need to work before she can afford to buy the computer, you can calculate this using the following steps:
$900 - $473 = $427
$427 / $7 = 61 hours of yard work
Result: Lena will need to work 61 hours before she can afford to buy the computer.
20,000,000+6,000,000+300,000+5,000+20+6
To find the simplest ratio, you must find the largest number they can both be divided by (greatest common factor, or GCF). However, 67 is a prime number, meaning its only factors are 67 and 1. That means there are no GCFs here other than 1, so, the simplest ratio here would be 33 over 67, or 33/67 in computer text. easy peasy!
Answer:
9
Step-by-step explanation:
4.05p + 14.40 = 4.5(p + 3)
4.05p + 14.40 = 4.5p + 13.5
14.40 - 13.5 = 4.5p - 4.05p
0.90 = 0.45p
0.90 / 0.45 = p
2 = p
