Question

Vihaan got 38/48 on his geography test. Sahaj got 80% on his geography test. Jada got 0.8125 on her geography test. Quinn thinks that Vihaan got a higher mark on his test than Sahaj and Jada.Is Quinn right? Prove whether he is right or wrong by showing your work (5 marks)

Answer 1

Vihaan got 38 in her geography test

Since the geography test has a total score of 48

Since Sahaj got 80% of it, then multiply 80/100 by 48 to find his score

`(80)/(100)*48=38.4`

Sahaj got 38.4 on the geography test

Since Jada got 0.8125 on her geography test, then multiply 0.8125 by 48 to find her score

`0.8125*48=39`

Jada got 39 on the geography test

The greatest one is Jada, then Sahaj, then Vihaan

Quinn thinks that Vihaan got the higher score

But Jada the one who got the higher score

Then Quinn is not right
