Пояснение:
a) To calculate the expression /169 - 3/0.36, we need to find the common denominator for the two fractions. The denominator for the first fraction is 169, while the denominator for the second fraction is 0.36, which is equivalent to 36/100. The common denominator is 16900. Now, we can rewrite the expression as (1/16900) - (3/16900). Subtracting the numerators, we get (-2/16900) as the answer.
b) The expression "uz - ya" implies that it involves variables and not enough information is provided to solve it.
c) To calculate 26.5", we need to convert inches to feet or centimeters. If we convert inches to centimeters, we multiply the inches value by 2.54. Therefore, 26.5" is equal to 67.31 cm.
d) The expression 500 times 10 divided by 32 can be simplified by performing the multiplication first: 500 * 10 = 5000. Then, we divide the result by 32: 5000 / 32 = 156.25.
Пример:
a) Calculate: /169 - 3/0.36
b) uz - ya
c) Calculate: 26.5"
d) Calculate: 500 times 10 divided by 32
Совет:
For the calculation of fractions, finding the common denominator is essential. It is important to be careful when dealing with variables in equations, as their values need to be provided to find a solution. When converting units, it is necessary to be aware of the conversion factors to ensure accuracy. For arithmetic operations, maintaining a systematic approach and following the correct order of operations is crucial.
