1 cm= 10 mm

7 cm= 70mm

difference between grasshopper and cockroach= 99mm - 70mm

                                                                            = 29mm

Answer 2

Answer: 29 mm or 2.9 cm

Step-by-step explanation:

Given : The length of grasshopper = 99 mm

The length of cockroach = 7 cm

We know that 1 cm = 10 mm

Then , the length of cockroach = 70 mm

Then , the difference in length between the insects is given by :-

$99\ mm-70\ mm=29\ mm$

Therefore , the difference in length between the insects = 29 mm or 2.9 cm
