Answer:

1 1/12

Explanation: you're gonna subtract (2-1) and (3/4-2/3) but first write the numerators as the least common denominator which is 12. so you do 9-8/12 = 1 1/12. If it needs to be an improper fraction then 13/12.

Answer:

The length of the mosquito in the picture is 117.6 mm.

Step-by-step explanation:

This question can be solved using a rule of three.

The real size of the mosquito is 16 mm, which is 100% = 1.

In the picture, the size is magnified 635%, so it is 100+635 = 735% = 7.35. So

16mm - 1

x mm - 7.35

x = 7.35*16 = 117.6

The length of the mosquito in the picture is 117.6 mm.
