Answer:
Yes, Nadiya is correct. By multiplying the numerator and denominator by 2, the first fraction equivalent to 2/10 is 4/20.
Step-by-step explanation:
To find a fraction equivalent to 2/10, we need to multiply (or divide) the numerator and denominator by the same nonzero whole number.
As we need an equivalent fraction with a denominator greater than 10, we will need to multiply and not divide.
The first nonzero whole number we have is 1. If we multiply the numerator and denominator by 1, we get 2/10. Obviously, 2/10 is equivalent to 2/10 but the denominator is not greater than 10, so it doesn't help us.
The next whole number is 2. When we multiply the numerator and denominator by 2, we get 4/20. The denominator is not less than 20.
If we keep going, we will get 6/30, 8/40 and so on.
Therefore, Nadiya is correct.
The correct answer is the first one.
