Question

Teri correctly spelled 60% of the words on the spelling test. How many words did she spell correctly for each word that she spelled wrong? What is the ratio of correctly to incorrectly spelled words?

Answer 1

3:2. 3 to 2 or 3/2

Answer 2

3 : 2

For every two wrong word she spelt she spelled 3 words correctly

Explanation:

Given that 60% of the words on the spelling test are correctly spelled by Teri

Let the number of words wrongly spelt be x and the number of words correctly spelt be y

Then
`(y)/(x+y)* 100= 60`

5y = 3x+3y

2y = 3x

`(y)/(x) = (3)/(2)`
