Question

a) Fill the blanks in the table and write the corresponding number indecimal form using ‘block’ information given below:b) Given the place value,write the number in decimal number:

Answer 1

(a) Here, in the block information, there are `142` dots in two blocks.
If we consider `100` dots as `1`, then we have,
`100/100+40/100+2/100=1+4/10+2/100`
So, Ones will be `1`, tenths will be `4` and hundredths will be `2`.
So, the corresponding number `= 1+4/10+2/100 = 1.42`

(b) Number in the place value,
`= 2**100+4**10+3**1+2**(1/10)+5**(1/100) `
`=200+40+3+0.2+0.05 = 243.25`
