Answer:
Number of years between 1950 and 2100 =

Answer:
$40
Step-by-step explanation:
25% is 1/4.
If 10 is 1/4 of the full amount, then you take 10 and multiply by 4 to get the full amount.
10 times 4 equals 40.
The prime factorization of the numerator, 315, is 5 x 3 x 3 x 7. That of the denominator, 1575 is 5 x 5 x 3 x 3 x 7. To convert the fraction to its lowest form, cancel all the factors that appear to both the numerator and denominator. We will be left with 1/5.
