Question

(20т 35кг * 10 - 13т 400кг : 100) - 25кг * 94

Answer 1

(20т 35кг × 10 - 13т 400кг ÷100)- 25кг × 94

1т=1000кг

(20035кг×10-13400÷100)=(200035-134)=199901-(25×94)

199901-2350=197551кг =197т 551 кг

Answer 2

To solve the given expression, let's break it down step by step:

1. 20t 35kg * 10: To calculate this, we multiply 20t (20 tons) by 10 and 35kg (35 kilograms) remains unchanged. 20t * 10 = 200t (tons) and 35kg stays the same.

So, the result of this step is 200t 35kg.

2. 13t 400kg : 100: To calculate this, we divide 13t (13 tons) by 100 and 400kg (400 kilograms) remains unchanged. 13t ÷ 100 = 0.13t (tons) and 400kg stays the same.

So, the result of this step is 0.13t 400kg.

3. Subtract the result of the second step from the result of the first step: 200t 35kg - 0.13t 400kg: To subtract these, we first convert 0.13t to kilograms (since 1 ton = 1000 kilograms): 0.13t = 0.13 * 1000kg = 130kg

Now, we perform the subtraction: 200t 35kg - 130kg 400kg

We can only subtract kilograms from kilograms, and tons from tons. So, we need to convert 200t to kilograms as well: 200t = 200 * 1000kg = 200000kg

Now, the subtraction becomes: 200000kg 35kg - 130kg 400kg

Subtracting: 199870kg - 130kg = 199740kg

So, the result of this step is 199740kg.

4. 25kg * 94: To calculate this, we multiply 25kg by 94: 25kg * 94 = 2350kg

Now, the final step is to subtract the result of the fourth step from the result of the third step: 199740kg - 2350kg = 197390kg

The final result is 197390 kilograms.
