Question

Resuelve
1. (3 1/4) X (2 5/6)
2. (1 4/5) X (7/4)

Answer 1

[tex]3 \: \: \frac{1}{4} = \frac{3 \times 4 + 1}{4} = \frac{12 + 1}{4} = \frac{13}{4} [/tex]

[tex]2 \: \: \frac{5}{6} = \frac{2 \times 6 + 5}{6} = \frac{12 + 5}{6} = \frac{17}{6} [/tex]

[tex] \frac{13}{4} \times \frac{17}{6} [/tex]

multiplicamos numerador con numerador y denomimador con denominador

[tex] \frac{221}{24} [/tex]

[tex]1 \: \: \frac{4}{5} = \frac{1 \times 5 + 4}{5} = \frac{5 + 4}{5} = \frac{9}{5} [/tex]

[tex] \frac{9}{5} \times \frac{7}{4} = \frac{63}{20} [/tex]
