1 | 5 | × | 5 |
9 | 8 |
Step 1: Analyze the operation
This is a multiplication problem, so we need to multiply the numerators and denominators of the fractions to get the product.
1 | 5 | × | 5 |
9 | 8 |
Step 2: Convert to improper form
It's difficult to perform arithmetic on mixed numbers, so we want to convert them to improper fractions. Use this formula for the conversion:
Whole × Denominator + Numerator = New Numerator
The first fraction needs to be converted to improper form. Plug in the values of the first fraction into the formula:
1 × 9 + 5 = 14
Re-writing the first fraction, we get 14/9.
14 | × | 5 |
9 | 8 |
Step 3: Multiply
Multiply the numerators across, and multiply the denominators across to get the product:
14 | × | 5 | = | 70 |
9 | 8 | 72 |
70 |
72 |
Step 4: Reduce
The fraction 70/72 is not in lowest terms, so we need to reduce it. List the factors of the numerator and denominator:
Factors of 70: 1, 2, 5, 7, 10, 14, 35, 70
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
2 is the largest factor of both 70 and 72, so we need to divide both the numerator and denominator by 2.
Numerator: 70 ÷ 2 = 35
Denominator: 72 ÷ 2 = 36
Write the new fraction:
35/36
