**Question:**
Find the other number if the sum of two numbers is 3/4 and one of the numbers is 1/8.

**Solution:**

To find the other number, we can use the concept of addition and subtraction of fractions.

Let's assume the other number as 'x'.

**Step 1:**
Write the given information as an equation:
1/8 + x = 3/4

**Step 2:**
To add fractions with different denominators, we need to find a common denominator.

The common denominator for 8 and 4 is 8.

**Step 3:**
Convert the fractions to have the same denominator:

1/8 + x = (1/8) * (2/2) + x = 2/16 + x

**Step 4:**
Combine the fractions:

2/16 + x = (2 + 16x) / 16

**Step 5:**
Now, we have the equation:

(2 + 16x) / 16 = 3/4

**Step 6:**
Cross-multiply to eliminate the fractions:

4(2 + 16x) = 3(16)

8 + 64x = 48

**Step 7:**
Simplify the equation:

64x = 48 - 8

64x = 40

**Step 8:**
Divide both sides of the equation by 64:

x = 40/64

**Step 9:**
Simplify the fraction:

x = 5/8

**Answer:**
The other number is 5/8.

X+1/8=3/4
x=3/4=_1/8
x=6/8_1/8
x=6_1/8 = x=5/8 I hope you understand
