Explanation:
Now let us check the given options.
1. 1\(\frac{1}{4}\) + 1\(\frac{1}{4}\) = 2\(\frac{3}{4}\)
\(\frac{5}{4}\) + \(\frac{5}{4}\)
Now add
\(\frac{10}{4}\) = 2\(\frac{2}{4}\)
That is 2\(\frac{2}{4}\) is not equal to 2\(\frac{3}{4}\).
Hence The correct answer is \(\frac{3}{10}\) + \(\frac{32}{100}\) = \(\frac{62}{100}\).

Answer:
Yes, Frankie’s equation is true.

Explanation:
Given,
1\(\frac{2}{3}\) = \(\frac{3}{3}\) + \(\frac{2}{3}\).
Now let us prove the given equation
1\(\frac{2}{3}\) = \(\frac{5}{3}\)
\(\frac{3}{3}\) + \(\frac{2}{3}\)
1 + \(\frac{2}{3}\)
Let us add
\(\frac{(3 + 2)}{3}\)
\(\frac{5}{3}\)
Hence \(\frac{5}{3}\) = \(\frac{5}{3}\)
Therefore Frankie’s equation is true.

b. Write three more equations for 1\(\frac{2}{3}\) that are all true and all different. Use only fractions with a denominator of 3 in your equations.
1\(\frac{2}{3}\) = ____________________
1\(\frac{2}{3}\) = ____________________
1\(\frac{2}{3}\) = ____________________
Answer:
The equations are 1 + \(\frac{1}{3}\) + \(\frac{1}{3}\)
1 + \(\frac{2}{3}\)
\(\frac{2}{3}\) + \(\frac{3}{3}\)

Explanation:
Here we need to write three more equations for 1\(\frac{2}{3}\) that are all true and all different.
The first one is 1 + \(\frac{1}{3}\) + \(\frac{1}{3}\) which is equal to 1\(\frac{2}{3}\)
1 + \(\frac{2}{3}\) = 1\(\frac{2}{3}\)
\(\frac{2}{3}\) + \(\frac{3}{3}\) = \(\frac{2}{3}\)
