Question

Antonio completed the right column of the table to help him find the sum of 2/9 and 1/5.

Answer 1

Step 1 is the first error

Explanation:

Given

`(2)/(9) + (1)/(5)`

Required

Which step contains the first error?

From the attachment, the first step is the first error.

This is so because the fractions can not be written as a fraction with a denominator of 14

Solving further:

`(2)/(9) + (1)/(5)`

Find Common Denominator 45

`(2*5)/(9*5) + (1*9)/(5*9)`

`(10)/(45) + (9)/(45)`

Add:

`(10 + 9)/(45)`

`(19)/(45)`
