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 
So here are 4 rules when it comes to exponents:
- When you raise a power to a power, you really just multiply the exponents:

- When you multiply 2 exponents of the same base, you add the exponents together:

- When you divide 2 exponents of the same base, you subtract the exponents:

- To convert a negative exponent into a positive one, flip it to its reciprocal:

<u>Part A:</u>

<u>Part B:</u>

<u>Part C:</u>
