of a mile on Tuesday, a 1/8 𝑜𝑓𝑎𝑚𝑖𝑙𝑒𝑜𝑛𝑊𝑒𝑑𝑛𝑒𝑠𝑑𝑎𝑦.𝑊h𝑜𝑟𝑎𝑛𝑚𝑜𝑟𝑒?𝐻𝑜𝑤𝑚𝑢𝑐h𝑚𝑜𝑟𝑒 did they run?

Answer 1

1/3 + 1/4 + 1/5 = 20/60 + 15/60 + 12/60 = 47/60 of a mile =about .783 mile for Sophia

1/7 + 4/9 + 1/8 = 56/504 + 284/504 + 63/504 = 403/504 = about .800 mile for Maverick

Maverick ran .017 mile more than Sophia

put the fractions over a common denominator then add the new numerators

3x4x5 = 60

7x9x8 = 504
