Answer 3

2/5 от 1 целой 7/8:

To find 2/5 of 1 and 7/8, we first need to convert 1 and 7/8 into a fraction with a common denominator.

1 = 8/8 (since 1 is equal to the whole)

Now we can calculate 2/5 of 8/8 + 7/8:

(2/5) * (8/8) + (2/5) * (7/8) = (16/40) + (14/40) = 30/40 = 3/4

So, 2/5 of 1 and 7/8 is equal to 3/4.

0.8 от 2.75 квадратных метров:

To find 0.8 of 2.75 square meters, we simply multiply 2.75 by 0.8:

2.75 * 0.8 = 2.2

So, 0.8 of 2.75 square meters is equal to 2.2 square meters.
