Answer 1

$\boxed{HoLa}$

Explicación paso a paso:

a)

$20 + 5 \times 38 = \\ \\ 20 + 190 = \\ \\ 210$

b)

$240 - 68 + 4 = \\ \\ 172 + 4 = \\ \\ 176$

c)

$250 + 5 \times 25 = \\ \\ 250 + 125 = \\ \\ 375$

d)

$120 + 84 - 3 \times 10 = \\ \\ 204 - 3 \times 10 = \\ \\ 204 - 30 = \\ \\ 174$

e)

$230 - 4 \times {5}^{2} + 14 = \\ \\ 230 - 4 \times 25 + 14 = \\ \\ 230 - 100 + 14 = \\ \\ 130 + 14 = \\ \\ 144$

f)

$0.42 \times 5 - 7 = \\ \\ 2.1 - 7 = \\ \\ - 4.9$

g)

$25 + 34 \times \frac{6}{3} = \\ \\ 25 + 34 \times 2 = \\ \\ 25 + 68 = \\ \\ 93$

h)

$\frac{17}{8} + 3 \times 6 = \\ \\ \frac{17}{8} + 8 = \\ \\ \frac{17}{8} + \frac{144}{8} = \\ \\ \frac{17 + 144}{8} = \\ \\ \frac{161}{8}$

i)

$\frac{3}{5} \times 8 + 5.25 = \\ \\ \frac{3 \times 8}{5} + 5.25 = \\ \\ \frac{24}{5} + 5.25 = \\ \\ \frac{24}{5} + \frac{21}{4} = \\ \\ \frac{96}{20} + \frac{105}{20} = \\ \\ \frac{96 + 105}{20} = \\ \\ \frac{201}{20}$

j)

$28 + 35 + 2.5 + 1.5 = \\ \\ 63 + 2.5 + 1.5 = \\ \\ 65.5 + 1.5 = \\ \\ 67$
