Answer:
4/1
First re-write the ratio as follows;Change the ratio sign to division (÷). i.e
2/20 ÷ 1/40 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) = 4/1
