a) 2/3 de 360
b) 1/8 de 92
c) 4/5 de 220
d) 9/7 de 63.
e) 15% de 720
f) 6% de 400
​

Answer 1

a) 2/3 de 360

360÷3=120

120x2= 240

b) 1/8 de 92

92÷8=11,5

c) 4/5 de 220

220÷5= 44

44x4= 176

d) 9/7 de 63

e) 15% de 720 = 108

f) 6% de 400 = 24

Answer 2

Resposta:

$a)~\frac{2}{3}~de~360=2.\frac{360}{3} =2.120=240\\ \\ b)~\frac{1}{8} ~de~92=1.\frac{92}{8} =92:8=11,5\\ \\ c)~\frac{4}{5} ~de~220=4.\frac{220}{5} =4.44=176\\ \\ d)~\frac{9}{7} ~de~63=9.\frac{63}{7} =9.9=81$

e) 15% de 720 =    $\frac{720.15}{100} =\frac{10800}{100} =108$

f) 6% de 400 =    $\frac{6.400}{100} =\frac{2400}{100} =24$
