Her grade as a mixed number in simplest form  = 1 \frac{1}{20}  \\

Morgan's grade written as a percent  = 105\%

GIVEN:- Morgan got 42 out of 40 points

TO FIND:-

a) Write her grade as a mixed number in the simplest form.

b) What is Morgan's grade written as a percent?

SOLUTION:-

  • The mixed form is represented by its quotient and remainder.

Her grade as a mixed number in simplest form

 =  \frac{42}{40}  \\

Dividing numerator and denominator by 2

 =  \frac{21}{20}  \\  =  1 \frac{1}{20}  \\

Percentage

 =  \frac{marks \: obtained}{total \: marks}  \times 100 \\  =  \frac{42}{40}  \times 100 \\   = \frac{4200}{40}  \\ =  105\%

Hence,

her grade as a mixed number in simplest form = 1 \frac{1}{20}  \\

Morgan's grade written as a per cent =105\%|
