Question

Vreau și eu rezolvarea exercitiului 3,va rog!

Answer 1

1,12 = a/50

112/100 = a/50

112/100 = 2a/100

112 = 2a

a = 56

4,24 = b/25

424/100 = b/25

424/100 = 4b/100

424 / 4b

b = 106

a+b = 56+106 = 162

Answer 2

3.

$1.12 = \frac{a}{50} | \times 50 = > 50 \times 1.12 = 50 \times \frac{a}{50} = > 56 = 50 \times \frac{a}{50} = > 56 = a = > a = 56.$

$4.24 = \frac{b}{25} | \times 25 = > 4.24 \times 25 = 25 \times \frac{b}{25} = > 106 = 25 \times \frac{b}{25} = > 106 = b = > b = 106$

$a + b = 56 + 106 = 162$
