Given that :- she use cup of flour=2 ¾ and cup of sugar= 1 3/8
total cup she used= cup of flour + cup of sugar
=2 ¾ + 1 3/8
to convert this mixed friction in normal friction we have to Multiply the denominator with the whole number then Add the numerator to the obtained product like 9 3/2= 21/2
similarly, 2 ¾ + 1 3/8 = 11 /4 +11 /8
now we have to find the LCM of denominator digits that are 4 and 8
LCM of 4 and 8 is 8
now when we solve this friction we get,
=22+11/8
=33/8 (answer)
she used total 33/8 cup.
