Question

NECESITO AYUDA CON ESTO :)

Answer 1

2)

$(3)(4) + (3)(5) = 12 + 15 = 27$

3)

$4(5) \div 4 - 3 = 20 \div 4 - 3 = 5 - 3 = 2$

4)

$(4 + 5) \div 3 = 9 \div 3 = 3$

5)

$\frac{2(3) + 6(4)}{3(5)} = \frac{6 + 24}{15} = \frac{30}{15} = 2$

6)

$\frac{3}{4}(4) + \frac{1}{3} (3) + \frac{2}{5} (5) = \frac{12}{4} + \frac{3}{3} + \frac{10}{5} = 3 + 1 + 2 = 6$

II)

$t = \frac{20 - 10}{5} \\ = \frac{10}{5} \\ = 2$
