Answer

Problem

The equivalent of a ratio of 2:5 is __.

Step

Given the ratio

\$2 : 5\$

Step

First, write the given ratio as a fraction

\$2/5\$

Step

Multiply the same number of antecedent and the consequent by a positive integer

\$(2 \times 3)/(5 \times 3)\$ = \$6/15\$

Step

Represent this fraction in the ratio form

\$ 6 : 15 \$

SumUp

Can you summarize what you’ve understood in the above steps?

Choice.A

Correct. It correctly represents the equivalent ratio when both parts are multiplied by 3

6 : 15

Choice.B

Incorrect. The ratio differs as 4 and 15 result from distinct non-zero multiples of 2 and 5

4 : 15

Choice.C

This is incorrect because it results in a ratio with one part as a fraction

15 : 6

Choice.D

Incorrect. The order of the terms is reversed, and it is not an equivalent ratio to 2 : 5

15 : 4
