Question

select all ratios equivalent to 2:5. 1:2 18:45 4:7

Explanation:

Step1: Simplify the given ratio

The given ratio is \(2:5\), which can be written as a fraction \(\frac{2}{5}\).

Step2: Check each option

• For \(1:2\), the fraction is \(\frac{1}{2}\). Since \(\frac{1}{2}

eq\frac{2}{5}\), \(1:2\) is not equivalent.

• For \(18:45\), simplify the fraction: \(\frac{18}{45}=\frac{18\div9}{45\div9}=\frac{2}{5}\). So \(18:45\) is equivalent to \(2:5\).
• For \(4:7\), the fraction is \(\frac{4}{7}\). Since \(\frac{4}{7}

eq\frac{2}{5}\), \(4:7\) is not equivalent.

Answer:

18:45
