Question 19.
Gerrie collects honey from a few beehives. She scoops out the honey with a small jar that holds \(\frac{1}{3}\) of a cup.
Over the last two weeks Gerrie has filled this jar 158 times. How many cups of honey has she collected?
Answer:
52\(\frac{2}{3}\) cups of honey,
Explanation:
Given Gerrie collects honey from a few beehives.
She scoops out the honey with a small jar that holds \(\frac{1}{3}\) of a cup. Over the last two weeks Gerrie has filled this jar 158 times.
So many cups of honey has she collected are
158 X \(\frac{1}{3}\) = \(\frac{158}{3}\)
numerator is greater than denominator so we write in
mixed fraction as \(\frac{52 X 3 + 2}{3}\),
therefore we get 52\(\frac{2}{3}\).
Question 20.
To finish sewing her tapestry, Petra needs 142 strips of cloth that are each one quarter of a yard. How many yards of cloth is that?
Answer:
35\(\frac{2}{4}\) yards of cloth,
Explanation:
Given to finish sewing her tapestry, Petra needs 142 strips of
cloth that are each one quarter of a yard.
So many yards of cloth is that 142 X \(\frac{1}{4}\) = \(\frac{142}{4}\) numerator is greater than denominator,
so we write in mixed fraction as \(\frac{35 X 4 + 2}{4}\),
therefore we get 35\(\frac{2}{4}\).
