Reduza as medidas ao grama e realizar operações.
A)1,3kg+143,6dag+2hg=
B)24,218kg×3g=
C)0,780dag:12g

Answer 1

A) 1,3kg + 143,6 dag + 2hg

1,3kg para g
>>>>>>>>>>>

1kg------------1.000g
1,3kg------------G

G = 1,3kg x 1.000g
.......___________
.................1kg

G = 1,3 x 1.000 g

G = 1.300g

143,6dag para g
>>>>>>>>>>>>>>

1dag----------------10g
143,6dag----------D

D = 143,6 dag x 10g
.......____________
.................1dag

D = 143,6 x 10 g

D = 1.436 g


2hg para g
>>>>>>>>>>>

1hg--------------100g
2hg---------------H

H = 2hg x 100g
......._________
................1hg

H = 2 x 100g

H = 200g

=> 1.300g + 1.436g + 200g
=> 2.736g + 200g
=> 2.936g

B) 24,218kg x 3g

24,218kg para g
>>>>>>>>>>>>>>>

1kg------------------1.000g
24,218kg---------K

K = 24,218kg x 1.000g
......._______________
.......................1kg

K = 24,218 x 1.000g

K = 24.218g


=> 24.218g x 3g
=> 72.654g

C) 0,78dag ÷ 12g

0,78 dag para g
>>>>>>>>>>>>>>>

1dag-----------------10g
0,780dag----------D

D = 0,780dag x 10g
.......____________
................1dag

D = 0,780 x 10g

D = 7,80 g

=> 7,80g ÷ 12g
=> 0,65g
