If Jacob complaints 4/8 his homework Jess completed 8/10 of her homework katie complete 12/15 of her homework. Did they complete the same amount prove if these fractions are equivalent using area models number sentences.

No

Step-by-step explanation:

if Jacob completes 4/8 then he finishes = 0.5 half of the homework

if Jess completes 8/10 then he finishes = 0.8 'th of the homework

if Katie completes 12/15 then he finishes = 0.8 'th of the homework

thus can be concluded Jess and Katie completed same amount of their homework - 80% of the total homework, but Jacob completed only half of his homework - 50%.
