Question

DAU 10 PUNCTE VA ROG AJUTAȚI-MĂ​

Answer 1

1.

a= 1,4

$2 \times a = 2 \times 1.4 = 2.8$

$10 \times a = 10 \times 1.4 = 14$

$25 \times a = 25 \times 1.4 = 35$

$100 \times a = 100 \times 1.4 = 140$

2.

a=12,15

$2 \times 12.15 = 24.3$

$10 \times 12.15 = 121.5$

$25 \times 12.15 = 303.75$

$100 \times 12.15 = 1215$

3.

a=125,521

$2 \times 125.521 = 251.042$

$10 \times 125.521 = 1255.21$

$25 \times 125.521 = 3138.025$

$100 \times 125.521 = 12552.1$

Answer 2

Răspuns:

2×1,4=2,8

10×1,4=14

25×1,4=35

100×1,4=140

2×12,15=24,3

10×12,15=121,5

25×12,5=312,5

100×12,15=1215

2×125,521=251,042

10×125,521=1255,21

25×125,521=3138,025

100×125,521=12552,1
