Answer 2

(1 1/5+2 3/10):1/2+(6 3/4-2 2/3):1 1/6 =10 1\2
1)1 1\5+2 3\10=1 2\10+2 3\10=3 5\10=3 1\2
2)6 3\4-2 2\3=6 9\12-2 8\12=4 1\12
3)3 1\2:1\2=7\2*2\1=7
4)4 1\12:1 1\6=49\12*6\7=7\2=3 1\2
5)7+3 1\2=10 1\2

Answer 3

Let's solve each of these arithmetic problems step by step:

1. 5 2/3 - 2 1/5:

First, we need to find a common denominator, which in this case is 15. Then, we can subtract the fractions:

5 2/3 = 5 * 3/3 + 2/3 = 15/3 + 2/3 = 17/3 2 1/5 = 2 * 5/5 + 1/5 = 10/5 + 1/5 = 11/5

Now, we can subtract:

17/3 - 11/5

To subtract these fractions, we need a common denominator, which is 15:

(17/3) * (5/5) - (11/5) * (3/3) = 85/15 - 33/15 = (85 - 33)/15 = 52/15

So, the result is 52/15, which can be expressed as a mixed number as well:

52/15 = 3 7/15

2. 2 5/6 + 1 3/10:

First, we need to find a common denominator, which in this case is 30. Then, we can add the fractions:

2 5/6 = 2 * 5/6 = 10/6 = 5/3 1 3/10 = 1 * 3/10 = 3/10

Now, we can add:

5/3 + 3/10

To add these fractions, we need a common denominator, which is 30:

(5/3) * (10/10) + (3/10) * (3/3) = 50/30 + 9/30 = (50 + 9)/30 = 59/30

So, the result is 59/30, which can be expressed as a mixed number as well:

59/30 = 1 29/30

3. 3 1/2 × 1 5/7:

To multiply these mixed numbers, first convert them to improper fractions:

3 1/2 = (3 * 2 + 1)/2 = 7/2 1 5/7 = (1 * 7 + 5)/7 = 12/7

Now, multiply the fractions:

(7/2) * (12/7)

The 7s in the numerators and denominators cancel out, leaving us with:

(1 * 12) / (2 * 1) = 12/2 = 6

So, the result is 6.

4. 2 3/4 ÷ 1 3/8:

To divide these mixed numbers, first convert them to improper fractions:

2 3/4 = (2 * 4 + 3)/4 = 11/4 1 3/8 = (1 * 8 + 3)/8 = 11/8

Now, divide the fractions:

(11/4) ÷ (11/8)

When you divide by a fraction, you can multiply by its reciprocal:

(11/4) * (8/11)

The 11s in the numerators and denominators cancel out, leaving us with:

(1 * 8) / (4 * 1) = 8/4 = 2

So, the result is 2.
