## Fractions: Sum of 2

Directions: Use the digits 0 to 9, at most one time each, to fill in the boxes so that the sum is equal to 2 wholes. Source: Joshua Nelson

## Benchmark Fractions

Directions: Use the digits 1 to 9, no more than once, to create three fractions that are as close to zero, one half and one as possible. NOTE: Close as possible is measured by adding up all the differences and making it the least possible value. Source: Darbie Valenti
