Red blood cells are really small...

One number is BIG: 7.5×10^4 mm = 75,000 mm = 75 meters
The other number is really SMALL: 7.5×10^-4 = 0.00075 mm

The negative exponent moves the decimal left instead of right.

Answer:

a = 4

b = 11

Step-by-step explanation:

To convert the recurring decimals into fraction we will follow the following process.

Given recurring decimal is 0.36363636....

Let x = 0.363636......... (1)

Multiply this decimal with 100.

100x = 36.36363636...........(2)

Now subtract expression (1) from expression (2)

100x = 36.363636.......

99x = 36

x = $\frac{36}{99}$

x = $\frac{4}{11}$

Since, $x=\frac{a}{b}=\frac{4}{11}$

a = 4 and b = 11 will be the answer.
