Question

На автомашине планировали перевезти сначала 3 целых восемь девятых т. груза, а потом ещё 2 целых одиннадцать восемнадцатых т. однако перевезли на 1 целую одну четвёртую меньше, чем предполагали. Сколько всего тонн груза перевезли на автомашине??

Answer 1

1.)планировали перевести всего 3 целых 8 одиннадцатых+ 2 целых 11 восемьнадцатых=6,5т.
2.)но перевезли на 1 целую одну четвертую меньше, т.е на 1,25 меньше, чем планировали
Получается что из общего числа задуманного мы вычитаем 1,25,т.е
6,5-1,25=5,25(т)
ответ:5,25т. груза всего перевезли на автомашине

Answer 2

Calculation of Total Weight of Cargo Transported

To calculate the total weight of cargo transported on the car, we need to determine the weight of each portion of cargo and then add them together.

The initial plan was to transport 3 and 8/9 tons of cargo first, followed by an additional 2 and 11/18 tons. However, the actual amount transported was 1 and 1/4 tons less than planned.

Let's calculate the total weight of cargo transported:

1. Convert the mixed fractions to improper fractions: - 3 and 8/9 tons = (3 * 9 + 8) / 9 = 35/9 tons - 2 and 11/18 tons = (2 * 18 + 11) / 18 = 47/18 tons - 1 and 1/4 tons less = (1 * 4 + 1) / 4 = 5/4 tons

2. Subtract the amount transported from the planned amount: - Planned amount: (35/9 + 47/18) tons - Actual amount: (35/9 + 47/18 - 5/4) tons

To simplify the calculation, we can find a common denominator for the fractions involved. The least common multiple (LCM) of 9, 18, and 4 is 36.

Converting the fractions to have a denominator of 36:

- (35/9) * (4/4) = 140/36 - (47/18) * (2/2) = 94/36 - (5/4) * (9/9) = 45/36

Subtracting the actual amount from the planned amount:

- (140/36 + 94/36 - 45/36) tons = 189/36 tons

Simplifying the fraction:

- 189/36 tons = 5 and 9/36 tons

Therefore, the total weight of cargo transported on the car is 5 and 9/36 tons.

Please note that the calculation assumes that the fractions provided are accurate and there are no additional factors affecting the weight of the cargo.

Answer:

The total weight of cargo transported on the car is 5 and 9/36 tons.
