Question

1. 6x35= 21x P=.....
P=.....

2. 13x N=2,6x75= .....
N= .....

3. 7,5x12= 30x N=....
N =....

4. 8,25 x16= 16,5xH=......
H=......

Answer 1

6x35 = 210
21xP= 210
P= 210 : 21
P = 10

2,6 x 75 = 195
13 x N = 195
N = 195 :13
N = 15

7,5 x 12 = 90
30 x N = 90
N = 90 ; 30
N = 3

8,25 x 16 = 132
16,5 x H = 132
H = 132 : 16,5
H = 8

Answer 2

1. 210=21p
<=>p= 210:21
= 10
2. 13N=195
<=>N=195:13b
=15
3. 90=30N
<=>N=90:30
=3
4. 132=16,5H
<=>H=132:16,5
=8
