Grandpa mick opened a pint of ice cream. he gave his youngest grandchild 1/5 of the ice cream and his middle grandchild 1/4 of the remaining ice cream. then, he gave his oldest grandchild 1/3 of the ice cream that was left after serving the others.
a. who got the most ice cream? how do you know? draw a picture to support your reasoning.
b. what fraction of the pint of ice cream will be left if grandpa mick serves himself the same amount as the second grandchild?

a. They all get the same quantity of ice cream.

b. Fraction of the pint of ice cream that will be left is 1/5

Step-by-step explanation:

Tape diagram is attached to support reasoning.

a. Youngest grandchild 1/5 of the ice cream

Middle grandchild 1/4 of the remaining ice

The remaining ice is 4/5.  

To get how much he gave to the middle grandchild we make 1/4 x 4/5

For fraction multiplication, multiply the numerators and then multiply the denominators to get

1×4/4×5=4/20

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 4 and 20 using

GCF(4,20) = 4

=1/4×4/5=1/5

We make the same for the last grand child.  

Remaining ice is 3/5 ( we discount the previous servings)

=1/3 x 3/5= 1/5

b. If Grandpa serves himself the same amount, 1/5,

That will be 1/5 for each person ( they are 4 persons),  we use 4/5

Then, will be left 1/5

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
