Question

Jalen tries to find the difference: 1 - 2 He makes an error. Highlight Jalen's first error, 1 9 13

Answer 1

the given expression is

`1(2)/(3)-(7)/(9)`

the calculation is given as follows,

`\begin{gathered} (5)/(3)-(7)/(9)=(10-7)/(9)=(1)/(3) \\ \end{gathered}`

first we jump from 7/9 to 1

so the length will be

= 1 - 7/ 9

= (9-7)/9

= 2/9

now we have 2/9

then we jump from 1 to 1 2/3 or 1 to 5/3

so ,

`\begin{gathered} 1(2)/(3)-1 \\ (5)/(3)-1 \\ (5-3)/(3)=(2)/(3) \end{gathered}`

now the total length is

2/9 + 2/3

`(2)/(9)+(2)/(3)=(2+6)/(9)=(8)/(9)`

it is clearly seen that at the place of 4/9 there will be 8/9

6/9 will be 8/9.
