Question

Read the scales of this balance.

Answer 1

Answer:

D) 1.200g

Step-by-step explanation:

from scale...

top line of scale = 0g

2nd line of scale = 1g

3rd line of scale = 0.2g

total from scale = 0 + 1 + .2 = 1.2g

Answer 2

Answer:

D.1.200 g

Step-by-step explanation:

We are given that unknown sample

We have to find the mass of unknown sample by reading the scales of given balance.

On first scale , reading=0 g

On second scale, reading=1g

On third scale, reading=0.2 g

Total mass=0+1+0.2=1.2 g

1.2 g can be written as 1.200 g because after decimal point when we write zeroes then it does not effect value of given number.

Hence, option D is true.
