Question

(7/30+8/45)+(2/45+1\30)

Answer 1

Ответ:

$\frac{22}{45}$ .

Объяснение:

$(\frac{7}{30}+\frac{8}{45} )+(\frac{2}{45} +\frac{1}{30} ) = \frac{8}{30} +\frac{10}{45} = \frac{4}{15} +\frac{2}{9} = \frac{4*3+2*5}{45} = \frac{12+10}{45} = \frac{22}{45}$

Answer 2

To solve the expression, we need to find a common denominator for each pair of fractions and then add them together. The common denominator for 30 and 45 is 90. Let's proceed with the calculations:

(7/30 + 8/45) + (2/45 + 1/30)

Step 1: Convert the fractions to have a common denominator of 90.

(7/30) = (7/30) * (3/3) = 21/90 (8/45) = (8/45) * (2/2) = 16/90 (2/45) = (2/45) * (2/2) = 4/90 (1/30) = (1/30) * (3/3) = 3/90

Step 2: Add the fractions with the same denominators.

(21/90 + 16/90) + (4/90 + 3/90)

Step 3: Add the fractions.

(37/90) + (7/90)

Step 4: Combine the fractions.

(37 + 7) / 90

Step 5: Final result:

44/90

However, we can simplify this fraction further. Both the numerator and denominator can be divided by their greatest common divisor, which is 2.

44/90 = (44/2) / (90/2) = 22/45

So, the simplified result of the expression is 22/45.
