Answer:

Step-by-step explanation:
<u>Given:</u>
2/20 : 1/40
A). First re-write the ratio as follows;
(i) Change the ratio sign to division (÷). i.e
2/20 ÷ 1/40
(ii) Solve the expression by changing the division to multiplication(×). This also means you will need to swap the numerator and the denominator of the second term. i.e (1 / 40) becomes (40 / 1)
(2/20) × (40 / 1) =
×
= 
B). Now convert the result from above to unit rate. A unit rate is a rate in which the denominator has a value of 1.
So to convert
to unit rate, we keep simplifying until the denominator becomes 1.
And since the denominator is already 1, there is no need for further simplification.
Therefore, 2/20 : 1/40 to unit rate is 
The equation would be “An= 8(4)^n”. Your answer would be equal to 8 times 4 to the 4th power, which is 2048
