Writing a ratio as a percentage without a calculator
In the past year, Isabel watchet 6 movies that she thought were very good. She watched 15 movies over the whole year of the movies she watched, what
percentage did she think were very good?

Answer 1

80%

Explanation:

So, if x movies are thought to be very good out of a total of y movies,

Then the required ratio is = x/y

= 44/ 55

=4/ 5

=0.80

=80/100

So if a total of 100 movies watched, 80 of them are thought to be very good.

Thus the required answer is 80%.
