Question

Jo wrote the numbers 2 1/2 3 1/7 1 5/6 in the form a/b what is the greatest number jo wrote

Answer 1

`(22)/(7)`

Explanation:

Let us convert all the numbers Jo wrote into decimals, then we can determine the greatest.

The first number is
`2(1)/(2)` . The form a/b is
`(2*2+1)/(2)=(5)/(2)=2.5`

The second number is
`3(1)/(7)` . The form a/b is
`(3*7+1)/(7)=(22)/(7)=3.14`

The third number is
`1(5)/(6)` . The form a/b is
`(1*6+5)/(6)=(11)/(6)=1.83`

The greatest number is
`(22)/(7)`
