3 класс. Итоговые контрольные работы за III четверть. Контрольная работа 1. Вариант 4

4*. В двух коробках было 48 ракушек. Когда из одной коробки в другую переложили 4 ракушки, ракушек в коробках стало поровну. Сколько ракушек было в каждой коробке сначала?

$1)\ 48 : 2 = \textcolor{#e03131}{\mathbf{24}}\text{ (р.)}$
$2)\ 24 + 4 = \textcolor{#e03131}{\mathbf{28}}\text{ (р.)}$
$3)\ 24 - 4 = \textcolor{#e03131}{\mathbf{20}}\text{ (р.)}$
Ответ: $\textcolor{#e03131}{\mathbf{28}}$ ракушек и $\textcolor{#e03131}{\mathbf{20}}$ ракушек.

3 класс. Итоговые контрольные работы за III четверть. Контрольная работа 2. Вариант 1

1. В одной коробке 36 кг конфет, а в другой в 3 раза меньше. Все конфеты разложили в пакеты, по 4 кг в каждый. Сколько пакетов заняли эти конфеты?

$1)\ 36 : 3 = \textcolor{#e03131}{\mathbf{12}}\text{ (кг)}$
$2)\ 36 + 12 = \textcolor{#e03131}{\mathbf{48}}\text{ (кг)}$
$3)\ 48 : 4 = \textcolor{#e03131}{\mathbf{12}}\text{ (п.)}$
Ответ: $\textcolor{#e03131}{\mathbf{12}}$ пакетов.

2. Железнодорожный мост имеет 3 пролёта. Длина первого пролёта 31 м, второго 29 м. Найди длину третьего пролёта, если длина всего моста 100 м.

$1)\ 31 + 29 = \textcolor{#e03131}{\mathbf{60}}\text{ (м)}$
$2)\ 100 - 60 = \textcolor{#e03131}{\mathbf{40}}\text{ (м)}$
Ответ: $\textcolor{#e03131}{\mathbf{40}}$ м.

3. С первого улья собрали 36 кг мёда, со второго — на 12 кг больше, чем с первого, а с третьего — в 2 раза меньше, чем со второго. Сколько килограммов мёда собрали с третьего улья?

$1)\ 36 + 12 = \textcolor{#e03131}{\mathbf{48}}\text{ (кг)}$
$2)\ 48 : 2 = \textcolor{#e03131}{\mathbf{24}}\text{ (кг)}$
Ответ: $\textcolor{#e03131}{\mathbf{24}}$ кг.
