Elena used math facts as an anchor to find the sum of 5 and 7. Her work is shown
In which step did her first error occur?
Step 1: The phrase "sum of" means addition,
Step 2 5+5 = 10
Step 3 Since 7 is 2 more than 5, 2 more need to be

O Step 1
O Step 2
O Step 3

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
