First, rewrite
3/10
and
7/25
so that they have a common denominator.

The common denominator would be 50.

To rewrite fractions with different denominators so that they have a common denominator, you need to find the least common multiple (LCM) of the two denominators. Here's how you can do it:

For the fractions 3/10 and 7/25, the denominators are 10 and 25. To find the LCM of 10 and 25, you can follow these steps:

Step 1: List the multiples of each denominator:
Multiples of 10: 10, 20, 30, 40, 50, ...
Multiples of 25: 25, 50, 75, 100, ...

Step 2: Find the first multiple that both denominators share, which is 50 in this case.

Now that we have the LCM, which is 50, we can rewrite the fractions with the common denominator:

3/10 = (3/10) * (5/5) = 15/50
7/25 = (7/25) * (2/2) = 14/50

So, when the fractions 3/10 and 7/25 are rewritten with a common denominator, they become 15/50 and 14/50, respectively.
