Answer 1

Respuesta:

$6 \frac{1}{2}$

Explicación paso a paso:

$3 \frac{1}{4} = \frac{3 \times 4 + 1}{4} = \frac{13}{4}$

$3 \frac{3}{8} = \frac{3 \times 8 + 3}{8} = \frac{27}{8}$

$1 \frac{1}{8} = \frac{1 \times 8 + 1}{8} = \frac{9}{8}$

$2.25 \times \frac{100}{100} = \frac{225}{100} = \frac{5}{4} = 1 \frac{1}{4}$

ya están preparados los términos

$(( \frac{13}{4} + \frac{27}{8} ) - \frac{5}{4} ) + \frac{9}{8}$

las paso a igual denominador

$(( \frac{104}{32} + \frac{108}{32} ) - \frac{40}{32} ) + \frac{36}{32}$

$( \frac{212}{32} - \frac{40}{32} ) = \frac{172}{32}$

$\frac{172}{32} + \frac{36}{32} = \frac{208}{32}$

$\frac{208}{32} = \frac{13}{2} = 6 \frac{1}{2}$

13/2=6 residuo 1
