Answer 1

Ответ:

Marat and his friend each got 4 candies because 8 candies divided equally between 2 people is 8/2 = 4 candies each.

Aruzhan ate 3/6 of the cake because 3 out of 6 equal parts is 3/6, which can be simplified to 1/2.

Akerke drank 1/2 of what was left, which means there is 1/2 x 3/4 = 3/8 of the original amount of juice left in the bottle.

To make the pie, you need 3/5 cup of flour and 2/5 cup of sugar, so the total cups of ingredients needed is 3/5 + 2/5 = 5/5, which is equal to 1 cup.

Nurbek ate 3/5 of his apples, and Taiman ate 1/2 of his apples. To compare, first find a common denominator, which is 10. So, Nurbek ate 6/10 of his apples, and Taiman ate 5/10 of his apples. Nurbek ate more apples because 6/10 is greater than 5/10.

The fraction of the number 7 that is its denominator is 1/7.

Kuandyk ate 3/4 of the pastry, so 1 - 3/4 = 1/4 of the pastry is left.

Daulet ate 3/4 of the cookies, which means there are 1 - 3/4 = 1/4 of the cookies left.

Armat collected 2/3 of the berries, so 1 - 2/3 = 1/3 of the berries are left to collect.

Zhansaya ate 1/3 of his portion, which means there is 1 - 1/3 = 2/3 of the pizza left for Symbat.
