Answer 2

Let's solve the math problems step by step:

1. 1/3 - 1/4 = (4/4)(1/3) - (3/3)(1/4) = 4/12 - 3/12 = 1/12

2. X - 1/2 = (1/3)X

To solve for X, let's isolate X on one side of the equation:

X - (1/2) = (1/3)X

Subtract (1/3)X from both sides:

X - (1/2) - (1/3)X = 0

Now, let's find a common denominator for (1/2) and (1/3), which is 6:

(3/6)X - (2/6) = 0

Combine the X terms:

(3/6)X - (2/6) = 0

Simplify the equation:

(1/6)X = 2/6

Now, let's isolate X by multiplying both sides by 6:

X = (2/6) * 6

X = 2

So, the value of X is 2.

3. 160 * (3/8) = 60

4. 13/4 + 4/13

To add these fractions, we need to find a common denominator, which is 52:

(13/4)(13/13) + (4/13)(4/4) = 169/52 + 16/52 = (169 + 16) / 52 = 185/52

Now, let's simplify the fraction:

185/52 = 3 and 29/52

5. 9/7 ÷ 63

To divide a fraction by a whole number, we can convert the whole number to a fraction with a denominator of 1:

9/7 ÷ 63/1 = 9/7 * 1/63

Now, let's multiply the fractions:

(9 * 1) / (7 * 63) = 9 / 441

6. 19/37 ÷ 38

To divide a fraction by a whole number, we can convert the whole number to a fraction with a denominator of 1:

19/37 ÷ 38/1 = 19/37 * 1/38

Now, let's multiply the fractions:

(19 * 1) / (37 * 38) = 19 / 1406

So, the answers are:

1. 1/3 - 1/4 = 1/12
2. X = 2
3. 160 * 3/8 = 60
4. 13/4 + 4/13 = 3 and 29/52
5. 9/7 ÷ 63 = 9/441
6. 19/37 ÷ 38 = 19/1406
