## Questions

### How do you add fractions with different denominators?

Find a common denominator, rewrite each fraction over it, then add the top numbers. For 1/2 + 1/3, use 6: 3/6 + 2/6 = 5/6.

### How do you divide fractions?

Flip the second fraction and multiply. For 3/4 ÷ 1/8, that is 3/4 × 8/1 = 24/4, which simplifies to 6.

### How do you turn a decimal into a fraction?

Write the digits over the matching power of ten and simplify: 0.125 = 125/1000 = 1/8. A decimal you have rounded, such as 0.333333, is not exactly one fraction, so the tool gives the closest fraction with a denominator up to 10,000.

### How do you change a mixed number into a fraction?

Multiply the whole number by the bottom number, add the top number, and keep the bottom number. For 1 1/2, that is (1 × 2 + 1) / 2 = 3/2.
