Answer:
51
Step-by-step explanation:
In multiplying fractions, you multiply the numerators and denominators.
51 / 2 * 21 / 3
can be reduced as
(17 / 2) * (21 / 1)
357 / 2 --> This is the answer based on the given.
Assume that its a mixed fraction:
5 1/2 * 2 1/3
11/2 * 7/3
= 77 /6
Volume of a cylinder = pi r^2 h where r = radius of the base and h = the height.
so if we are given a radius of 2 cm and a volume of 180 cm^3 we work out the height as follows:-
180 = pi * 2^2 * h
h = 180 / (pi*2^2)
height h = 180 / 4pi = 14.32 cm to nearest hundredth
Divide 12 by 9 to get your answer which is 1.333...
So, per each kilogram bag of mangoes, the cost is $1.3 repeating or just $1.33
