Answer :
The correct answer is:
An equivalent ratio would be 4/10, and the number of cattle would be 136,000.
Explanation:
The question asks for an equivalent ratio. This means a fraction that is equivalent to the fraction between 700-799, which is 2/5.
To create an equivalent fraction, we multiply the numerator and denominator by the same number. Multiplying both by 2, we get
(2*2)/(5*2) = 4/10.
Tenths are useful when dealing with thousands, because taking a tenth involves getting rid of a zero. This means that 1/10 would be 34000; 4/10 would be 4 times that: 4(34000) = 136000.
