Quizizz, Fractions and Using Estimation Fraction Benchmarks

Using fraction benchmarks can help quickly estimate fractions. What are the numbers we will be using to estimate based on this picture?

•  $\frac{1}{4}\ and\ \frac{2}{3}$  

•  $\frac{1}{2}\ and\ \frac{5}{7}$  

•  $1\ and\ \frac{1}{3}$  

•  $1\ and\ \frac{1}{2}$
