Answer :

Sure, let's write the numerals for the given numbers step-by-step.

### (a) Forty two lakh seventy thousand eight

1. Start with the largest unit, which is "lakh". Here, we have "Forty two lakh".
- Forty two lakh (42,00,000)

2. Then, "seventy thousand" needs to be added to this.
- Seventy thousand (70,000)
- So, combining this with the previous value: [tex]\( \text{42,00,000} + \text{70,000} = 42,70,000 \)[/tex].

3. Lastly, we add "eight".
- Eight (8)
- Adding this to the previous total: [tex]\( \text{42,70,000} + 8 = 42,70,008 \)[/tex].

So, Forty two lakh seventy thousand eight is written as 42,70,008.

### (b) Seven crore sixty thousand fifty five

1. Start with the largest unit, which is "crore". Here, we have "Seven crore".
- Seven crore (7,00,00,000)

2. Then, "sixty thousand" is added to this.
- Sixty thousand (60,000)
- So, combining this with the previous value: [tex]\( \text{7,00,00,000} + \text{60,000} = 7,00,60,000 \)[/tex].

3. Lastly, we add "fifty five".
- Fifty five (55)
- Adding this to the previous total: [tex]\( \text{7,00,60,000} + 55 = 7,00,60,055 \)[/tex].

So, Seven crore sixty thousand fifty five is written as 7,00,60,055.

Hence, the numerals for the given numbers are:
- (a) 42,70,008
- (b) 7,00,60,055
