В)44,46

Answer 2

To solve these equations, let's perform the calculations step by step:

A) 1.1/7 * 2.1/3

To multiply fractions, we multiply the numerators (top numbers) together and the denominators (bottom numbers) together. The result will be a fraction:

(1.1/7) * (2.1/3) = (1.1 * 2.1) / (7 * 3) = 2.31 / 21 = 0.11 (rounded to two decimal places)

Therefore, 1.1/7 * 2.1/3 is approximately equal to 0.11.

B) 6 * 13.24

To multiply a whole number by a decimal number, we multiply them as usual:

6 * 13.24 = 79.44

Therefore, 6 multiplied by 13.24 equals 79.44.

C) 5.7 * 7.8

To multiply two decimal numbers, we multiply them as usual:

5.7 * 7.8 = 44.46

Therefore, 5.7 multiplied by 7.8 equals 44.46.
