Question

3 1/8+ 2 11/16и7 5/8-2 1/16 пж​

Answer 1

3​$\frac{1}{8}$ + 2$\frac{11}{16}$ = 5$\frac{13}{16}$

7$\frac{5}{8}$ - 2$\frac{1}{16}$ = 5$\frac{9}{16}$

Answer 2

To solve this arithmetic expression, you need to add and subtract the mixed numbers. Here's the step-by-step calculation:

1. Add 3 1/8 and 2 11/16: 3 1/8 + 2 11/16

To add these mixed numbers, you can first find a common denominator, which in this case is 16. Then, add the whole numbers and fractions separately:

3 + 2 = 5 (whole numbers) (1/8 + 11/16)

Now, you need to find a common denominator for the fractions. In this case, it's 16:

1/8 * 2 = 2/16 11/16 (no change needed)

Now, you can add the fractions:

2/16 + 11/16 = 13/16

So, 3 1/8 + 2 11/16 = 5 13/16.

2. Subtract 7 5/8 and 2 1/16: 7 5/8 - 2 1/16

Again, find a common denominator, which is 8 in this case:

7 - 2 = 5 (whole numbers) (5/8 - 1/16)

Now, find a common denominator for the fractions, which is 16:

5/8 * 2 = 10/16 1/16 (no change needed)

Now, subtract the fractions:

10/16 - 1/16 = 9/16

So, 7 5/8 - 2 1/16 = 5 9/16.

Now that you have both results:

3 1/8 + 2 11/16 = 5 13/16 7 5/8 - 2 1/16 = 5 9/16

You can perform the final operations you mentioned (adding and subtracting):

5 13/16 + 5 9/16 = 11 22/16

You can simplify the final fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:

(11/2) / (22/2) = 11/2

So, the final result is 11/2 or 5.5.
