What is the answer to 2 3/8 ÷ 1 1/4
OLEGan [10]
2\frac{3}{8} ÷ 1\frac{1}{4} equals 1\frac{9}{10}.

First, convert 2 \frac{3}{8} to improper fraction. Use this rule: a \frac{b}{c} = \frac{ac+b}{c}. Your problem should look like: \frac{2x8+3}{8} ÷ 1\frac{1}{4}.
Second, simplify 2 x 8 to get 16. Your problem should look like: \frac{16+3}{8} ÷ 1 \frac{1}{4}.
Third, simplify 16 + 3 to get 19. Your problem should look like: \frac{19}{8} ÷ 1 \frac{1}{4}.
Fourth, convert 1\frac{1}{4} to improper fraction. Use the same rule as earlier. Your problem should look like: \frac{19}{8} ÷ \frac{4+1}{4}.
Fifth, simplify 4 + 1 to get 5. Your problem should look like: \frac{19}{8} ÷ \frac{5}{4}.
Sixth, apply this rule: a ÷ \frac{b}{c} = a × \frac{c}{b}. Your problem should look like: \frac{19}{8} × \frac{4}{5}.
Seventh, apply this rule: \frac{a}{b} × \frac{c}{d} = \frac{ac}{bd}. Your problem should look like: \frac{19x4}{8x5}.
Eighth, simplify 19 × 4 to get 76. Your problem should look like: \frac{76}{8x5}.
Ninth, simplify 8 × 5 to get 40. Your problem should look like: \frac{76}{40}.
Tenth, simplify. Your problem should look like: \frac{19}{10}.
Eleventh, convert to mixed fraction. Your problem should look like: 1 \frac{9}{10} which is the answer.

Answer as mixed number form: 1\frac{9}{10}.
Answer as exact form: \frac{19}{10}.
Answer as decimal form: 1.9.
