Step-by-step explanation:
To write the fraction (3)/(14) as an equivalent fraction with a denominator of 70, you need to find a number that you can multiply 14 by to get 70. First, divide 70 by 14, which gives you 5. This means that both the numerator and the denominator of (3)/(14) must be multiplied by 5 to keep the fraction equivalent while changing its denominator to 70.
So, the calculation to find the new numerator would be 3 * 5 = 15. Now, you have the equivalent fraction: (15)/(70). Remember, an equivalent fraction represents the same value or proportion of the whole, you're simply adjusting the terms to fit a new denominator.
