Answer:
The answer to your question is 64/100 and 65/100
Step-by-step explanation:
Data
Common denominator of 16/25 and 13/20
Process
1.- Find the least common factor of 25 and 20.
25 20 2
25 10 2
25 5 5
5 1 5
1
L.C.F. = 2 x 2 x 5 x 5 = 100
2.- Convert each fraction to the denominator 100
100 / 25 = 4
16/25 = (16 x 4) / 100
= 64/100
100 / 20 = 5
13/20 = (13 x 5)/100
= 65/100
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.
Recall that for 
, we have
Replace 
with 
and we get
Lastly, multiply this by 
, so that
C cubed minus the product of five and Q +4
=
C^3 - [5(Q +4)]
