Answer 1

1/20 x 5= 5/100 = 0,05=5%

3/50 × 2 =6/100=0,06=6%

9/25 ×4 = 36/100 =0,36=36%

6/10 ×10 =60/100 = 0,60=60%

pregunta8

11%de 7000

$\frac{11 \times 7000}{100} = 11 \times 70 = 770$

26%de 500

$\frac{26 \times 500}{100} = 26 \times 5 = 130$

45%de 200

$\frac{45 \times 200}{100} = 45 \times 2 = 90$

78%de 650

$\frac{78 \times 650}{100 } = \frac{39 \times 650}{50} = \\ 39 \times 13 = 507$

32%de 1250

$\frac{32 \times 1250}{100} = \frac{8 \times1250 }{25} = \\ 8 \times 50 = 400$

a)15/100 × 1400 = 15 × 14 = 210

b)3/100 x 800 = 3 x 8 = 24

c)96/100 x 350 = 24/25 x 350 = 24 x 14 = 336

d)10/100 x 20000 = 2000
