Question

efetue as divisões: a) 4,88 ÷ 1,6 = b) 416 ÷ 32,5 = c) 13,11÷ 5,7 = d) 90 , 3 ÷3 =

Answer 1

a)

$4.88 \div 1.6 \\ \\ = \frac{488}{100} \div \frac{16}{10} \\ \\ = \frac{488}{100} \times \frac{10}{16} \\ \\ = \frac{4880}{1600} \\ \\ = \frac{488}{160} \\ \\ = 3.05$

b)

$416 \div 32.5 \\ \\ = \frac{416}{1} \times \frac{10}{325} \\ \\ = \frac{4160}{325} \\ \\ = 12.8$

c)

$13.11 \div 5.7 \\ \\ = \frac{1311}{100} \times \frac{10}{57} \\ \\ = \frac{13110}{5700} \\ \\ = \frac{1311}{570} \\ \\ = 2.3$

d)

$90.3 \div 3 \\ \\ = \frac{903}{10} \times \frac{1}{3} \\ \\ = \frac{903}{30} \\ \\ = 30.1$
